AEG Feature of the Month :

                        G&G UMG review

We recently received a working prototype of the NEW G&G UMG. Having personally handled and shot a real UMP .45, we were very eager to compare this gun with our experience with the real one as well as evaluate it as an AEG.

Appearance

The G&G UMG is an extremely detailed and attractive AEG. The ABS plastic body is very solid and has a flat matte look to it with similar feel as the Classic Army CA36C ABS. G&G put a lot of detail into this gun from the correct positioning of the markings (no H&K trademarks) on the gun to the mock trigger assembly pins in the lower receiver just like where they should be on a real H&K UMP. To keep the gun from having problems from importing in to the US, the markings are changed to prevent trademark violations. Instead of HK on the side of the gun like the real gun, they have GG (For Guay Guay or G&G as we know it) . Instead of UMP, they named it "UMG" which, according to G&G, stands for "Uber Machine Gun". They also added the “6mm auto” markings on the bolt instead of .45 cal, .40cal, or 9mm. These small details make the look and feel of the UMG extremely authentic. The gun also comes equipped with side and bottom rails to allow the addition of a vertical foregrip, lights, lasers, or any railed accessory you can imagine and a top rail to add your favorite optic. The stock folds to the side and locks solidly into place. Overall, the appearance is top notch and the attention to detail will appeal to the most discerning airsofters.

Side and under rails are included on this AEG.

The UMG has G36 style selector that is ambidextrous.

Here you can see the detail of the gun with "6mm Auto" engraved on the UMG's bolt along with the fake trigger assembly pins in the lower receiver.

Performance

The overall performance is much similar to Tokyo Marui AEG's. Out of the box, this sample fires smoothly, shooting approximately 260-280 fps with 0.20g Excel BB's. The gun draws about 11-12.5 AMPs with the stock spring. Since this is a pre-production model, we are uncertain if this will be the actual velocity of the production gun but it is decent for a compact stock weapon. The gun’s battery compartment can fit an 8.4V 600mah NiCad 1050mah NiMH stick battery. To access this area, you must fold the stock and then open the small door in the back. This makes changing batteries a breeze. The compartment size limitation will require an entirely new configuration of custom battery if you need more power. The GnG manual shows that a custom configured 9.6V 1100mah NiCad battery using the same cells as that of an MP5SD6 custom battery will fit the compartment. However, our experience indicates that the 8.4V 1050 mah NiMH battery performance should be superior, especially if you don’t own a good charger that will maximize the performance of the 1100mah NiCad cells. We will have to explore further the battery potential of this gun.

Here you can see the battery access from the rear view of the AEG. With the stock folded open, you can open the small door to easily get the battery in and out.

This gearbox is virtually IDENTICAL in appearance and dimensions to the Ver III gearbox. Looking at it you would think you opened a TM or CA G36C. The way the motor is attached is very similar as are the internals. Unlike most Ver III gearboxes, the spring guide usually pops out when you crack it open. The G&G UMG actually stays put. They use the G&G Ver III spring guide without bearing and as you can see on the image on the upper right. It stays put even with the spring compressed with the piston. The UMG comes standard with a polycarb type piston, piston head, metal bushings, reinforced gearset (standard ratio) and reinforced spring guide.

G&G also uses their high torque motors in the AEG that produces a decent rate of fire. With an 8.4v battery, the gun delivers a nice 600 rounds per minute and at 9.6v, it’s around 800 rpm. We did upgrade the UMG with 2 types of springs. The first, an M100 by Systema. The results were not impressive but I am hoping it was either due to the gun being a prototype or, honestly, because we rushed through the upgrade. The gun went from shooting 270fps to 300 with an M100. Rate of fire was about the same, a little slower but not by much. It had a 13-15Amp draw and had a nice deep sound when firing! With the Guarder SP120 upgrade, it only fired 320fps with the same BB (Excel 0.20g non Bio). It had a 14-16Amp draw and a rate of fire of approximately 500-600 rounds per minute.

The base plate is attached just like the TM and CA G36C. You only need to remove the one large screw on the bottom to free the gearbox. The other 2 screws hold the base plate to the lower receiver.

Features

The UMG has several features that enhance the performance, look, and the overall feel of the AEG. Let's start with some of the performance parts. The hopup unit is a one piece hopup system that is all metal. The adjustment lever is accessible behind the ejection port like most AEG's. Just like a TM G3 SG-1, MC-51 or even a CA33E, the hopup adjustment lever can be accessed when the charging handle on the weapon is cocked back. You can lock open the ejection port like the real thing.

Here you can see the cocking handle is locked back and up like an MP5, G3 or PSG-1. The cocking knob even rocks back a few degrees as you pull on it, just like on the real H&K UMP – this feature demonstrates the incredible details that GnG included with the gun that is functionally unnecessary in an AEG but faithful to the authentic UMP.

The hopup unit is exposed along with the hopup adjustment lever. To adjust more hop, you slide the black lever forward or towards the barrel. For less, slide it to the rear of the gun.

Not only can you lock the bolt open by charging the cocking lever back and rotating it up like on any Airsoft MP5, you can also lock it open with the bolt catch. Just like the real gun, this bolt catch actually works. Pull back the charging lever and press the bottom of the bolt catch and the bolt will lock open. To unlock, you can smack the top round part of the bolt catch and the bolt will snap forward. We did this quite a bit and the bolt didn’t break off as they sometimes do on MP5’s. Once again, this authentic feature does nothing for AEG performance or functionality but is very cool nonetheless.

The UMG breaks open almost identically to the real gun where the upper receiver can be rocked up from the lower receiver. This makes breaking down the AEG for an upgrade or switching inner barrels a very simple task. There are a few key things to be aware of when performing this procedure. You can see in these pictures the steps to field stripping the G&G UMG.

1. Remove the rear body pin

2. Before removing the lower receiver, you must push hopup unit forward to clear the AEG's nozzle from the hopup chamber (the hopup unit has a spring in front like a P90, G36C and an AUG).

3. As you push the hopup unit forward, you can swing the lower receiver down. Once it is in this position, the hopup chamber should be clear of the nozzle.

4. Now you can unhinge the lower from the upper receiver. If you need to access the inner barrel, it comes out very similar to the G36. Just push it in, twist it slightly and it will slide out.

The rear sights are adjustable with hex screws.

Rear sight can also switch from standard sight to ghost ring.

The gun comes with a 70 round standard mag and will have 530 round hicaps available soon after the release. The magazine is the only part lacks complete authenticity. The real UMP magazine has a thin clear plastic window strip in the middle so you can view your ammo status.

Optional

The gun will have a quick detach mock silencer available but it will not be included with the gun.

Here is a picture with the silencer on the UMG.

Overall

The G&G UMG is an extremely high quality and compact AEG and one of the most faithful reproductions of the actual firearm available on the airsoft market. The level of detail and the overall construction make this a definite buy. The only issue we encountered was the low velocity after a quickie upgrade. We highly doubt that the issue is with the gun although we won’t know for sure till they become available in quantity and we do more work on them. Meanwhile, we’ll keep tinkering with the gun and update the report if there is any new information.

Colt 1911 MkIV Series 70 - Western Arms

I've been very fortunate to get my hands on a lot of Western Arm's excellent Gas Blow Back pistols over the last few months, thanks to Elite Airsoft, but I was very pleasantly surprised recently, when a couple of Shibuya Custom Works limited editions arrived in a big box (Christmas HAD come early!).
These guns are made in limited numbers and are not, officially, available outside Japan. Both were Colt 1911 based guns, the Wilson based Vreaker V12 and, this one, the Colt 1911 MkIV Series 70 Government.

Although not a big 1911 fan, I was very interested to see this gun as Western Arms have made much of the new features present on it, which include a system to allow the hammer to be dropped without firing the gun (At last you can decock a 1911!) and a hop-up which doesn't require disassembly to adjust.

In the Box

The SCW guns come in smart Grey boxes, with "SCW" in white on the top and a sticker on one end to indicate the contents. Businesslike, but a bit more finished than the normal uncoloured cardboard.


Inside, however, it's WA business as usual, with the gun, a bag of paper work, including the manual and a target, a small bag of 6mm BBs, a couple of Allen keys and the gun. Unusual to the pukka 1911s (rather than the Infinities and the like) is a barrel bushing wrench - more on that later.

First Impressions

First impressions are very favourable.
This is one of the most attractive airsoft pistols I have ever seen, despite being very plain. The quality shines out of it, from the bright chamber cover to the excellent wood effect grips (undoubtedly the best plastic wood I have ever seen) to the flawless finish of the heavyweight material.

The gun has a nice balance in the hand and being a single stacker (just 15 rounds in the slim magazine) is pleasantly slim, which I like, but that will vary from person to person.

There are few markings, but the ones present are quite shallow and thin, a bit like a KSC. They are, however, sharply engraved.

Closer Look

The 1911 is made mainly of Heavyweight ABS and has a cold feel to the touch. Overall finish is flawless, with no seams and none of the pitting on the metal parts seen on some of the more recent Infinities.
At 860g, the gun is not a real heavyweight, but it feels very solid and well balanced in the hand. Being much slimmer than a double stack Infinity or Para-Ordnance, the difference in weight certainly doesn't lend an air of fragility to the 1911.

The simple, button magazine releases the magazine smoothly to reveal a plain (like the rest of the gun) black 15 BB capacity single row magazine.

The outer barrel is metal, although quite thin and features the slight swelling at the end, typical of the 1911 design. It's quite different to the cone-shaped barrel of the Infinities and the, otherwise similar, Vreaker.

There aren't a lot of markings on the gun and the ones that are present are a little shallow, by comparison with WA's usual finish.
On the left of the slide the markings read "COLT MKIV SERIES 70" with, below, "GOVERNMENT MODEL" and ".45 AUTOMATIC CALIBER" at the bottom. A Colt rampant logo is aligned with all three lines of text.
On the right of the slide the text reads "COLT GOVERNMENT MODEL". The chamber cover is engraved with " COLT .45 AUTO", MKIV/SERIES '70" in two rows. On the frame, just above the grip, in small font, is the text "COLT'S PT. F.A. MFG. CO. HARTFORD, CONN. U.S.A.".
On the grips are small gold medallions bearing the word "Colt" and the rampant horse logo. It's worth repeating just how good these plastic grips look, although I'm sure some real wood grips would improve the tactile aspects and look even better - Reports suggest real steel grips are a straight swap.
There are grooved serrations on the rear of the slide which make it very easy to rack, helped by the very smooth action of the slide itself.
The grip safety is quite discrete compared to the wild Beaver tails on some of the 1911s derivatives and the trigger is minimalism personified, being JUST enough to work. The trigger feel is very good, too.
There's a single (left mounted for right handed operation) thumb operated hammer safety, which works with the hammer cocked, much like any other 1911 derived gun, or any other single action automatic, in fact.
The sights are extremely simple, with no adjustment or dots or serrations, with just a square notched blade and the back and a single, quite broad, blade at the front.
The 'transfer hammer' mechanism (first seen on the Beretta 1934) works well, letting you decock the single action 1911, simply by pulling the trigger and letting the hammer down gently. However, I could not work this single handed, having to use one hand to pull the trigger, whilst engaging the grip safety and the other to lower the hammer.
Much is made of this being WA's first gun where you can adjust the Hop-Up without stripping the gun down and it is true. Like KSCs, you simply open the slide and adjust the hop over the barrel. In this case, there's a allen bolt which needs adjusting with an Allen key. I didn't fiddle, but I've read other reports which suggest it's still quite tricky to get the Hop-Up set just as you want.

Shooting Impressions

Gassing the magazine was easy, as was loading the 15 or so BBs (in a single stack) and the gun gives off a very satisfying crack and a sharp, snappy recoil when fired.
I was slightly stunned by the accuracy of the very simple sights.
The groupings were good, but they were grouped exactly around the point where I aimed, rather than high or low or left or right. I popped off a few more groups on a target with some small roundels and was able to place tight groupings around the centres of the small targets as easily as around the bull on the bigger targets.


Click on image for bigger version in separate window. Carrying out my standard 5m/6 round, off hand test, the grouping was 1.5 inches (3.5 CMs) in diameter and this was repeated or bettered on every occasion that I fired the gun.
Update July 2005 I received a second Series 70 in a batch of guns for review in July 2005 and was able to carry out my velocity and trigger pull tests.
Over 10 shots, the 1911 Series 70 averaged 301 fps (using Abbey Ultra gas and Excel .2g BBs) indoors (at 21C).

Shot	FPS
1	309.6
2	302.6
3	304.1
4	302.1
5	301.6
6	298.6
7	295.0
8	306.6
9	295.2
10	295.8

I also achieved a best 5 grouping of .7 inch (1.7CM) with this example of the 1911 Series 70.
Trigger pull was 670g (24 Oz), which is a lightish weight pull for a GBB.

Take Down

Take down is a faithful replication of the real steel process.
After removing the magazine, move to the front of the slide and depress the chequered button, under the barrel. With this depressed, use the bushing spanner to open the bushing with a quarter turn anti-clockwise.


Slide the slide back until it locks and unscrew the outer barrel. Then remove the slide lock (push it through the frame from the side opposite where it locks the slide) and let the slide and inner barrel slide off the frame. Once off, the inner barrel/chamber can be removed from the slide.

Conclusions

I'm not a big 1911 enthusiast, but this gun is one of the very best airsoft pistols I have ever handled.
Visually, it's excellent, it feels solid in the hand and shoots with exceptional accuracy despite its simple sights.

If you're looking for a 1911 or just a good, solid, no-nonsense gas blowback pistol, you can do no better than this gun.
The only negatives are the price (a Ltd Infinity is cheaper) and the fact that it's probably already sold out by the time you read this review...

G&P M4A1 Marine
G&P M4A1 Marine AEG Review
Published on: Sat 02 Dec, 2006 6:00 pm
Author: Paul "Caine"Pfiffner
Category: Assault Rifles

Technical Specs:
Model: G&P M4 Marine
Manufacturer: G&P
Cost: $305 (HK) $350 (US)

Interior: 10-10

• Reinforced 7mm Gearbox complete with ball bearing bushings.
• One Piece Metal Hop-Up Chamber (soft type rubber bucking)
• Sector Gear Cam Chip (delays the nozzle by starting the throw of the tappet plate increases feeding reliability)
• Very nice flat gear set. (On par with Systema)
• Aluminum Cylinder Head (Looks almost like a Prometheus)
• Aluminum Nozzle (with o-ring inner seal)
• Aluminum Bearing Spring Guide
• PDI 150 (or equivalent)

These items immediately stuck out in my mind as "whoa" factors for a competitively priced AEG. These would all be upgraded parts in most AEGs available on the market today. The sector chip is the first I've seen in a production replica.
This is the nicest mechbox I have opened up, period. I was simply in awe at what G&P had tossed in there. It was as though they decided to just give you everything you needed up front so you could get on with playing and buying more gear, instead of buying internals to be rock solid. This is for all general purposes a completely upgraded box much akin to the Systema full boxes you can pick up for $300, except it is already in the replica. The only way you can truly appreciate the quality is to know what you are looking at or simply by pulling the trigger yourself. This G&P offering is "golden" on the inside. They delivered the goods.

Exterior: 9.9-10

• Everything that is supposed to be metal is.
• One-Piece Barrel w/gas tube.
• Clear and Clean Laser Engraving
• Carry Handle is heavier and better made than the CA's and G&G's
• Telescoping Stock tube's metal collar is threadable (less stress on mechbox will locking it down)
• Foregrip and pistol grip are extremely flat in color.
• 4 screw pistol grip attachment to mechbox. (rather than 2...no more cracking)
• Delta Ring/Spring has a very high tension. (No loose grips)
• Heatsink Style motor plate a'la CA style.
• G&P Midcap Magazine
• Metal SR-16 Type Flashhider
• Metal

There are only two real issues I have with the exterior of the replica. G&P (or could just be the one I received) has a shiney black telescoping buttstock. A little flat black paint would remedy this in a flash, but still yet, it is there. Also G&P went with a 14mm+ thread instead of the common 14mm-. This will require a little more looking when the time comes to change flashhiders.
Overall: 10-10 Overall, this is the best option available for a first-time or veteran buyer for an m4. G&P hit a homerun with their attention to detail. With all the parts that G&P included with this replica, you would be doing yourself a disservice not to pick one up. They are a pleasure to shoot, look great, perform great, and are rock solid to boot. It seems that G&P succeeded what few other manufacturers even attempt these days: Quality and Affordability.

There are many factors that make a replica a "10" in my book. I have owned several manufacturers products, but none yet has produced an M4 as quality oriented as G&P

Review on The G&G RK-104

The GuayGuay (G&G) RK104 is an airsoft replica of the AK-104, a shortened 7.62X39mm assault rifle produced for the Russian military. The Kalashnikov-designed AK-100 series is an evolutionary improvement on the AK-74 series that currently equips former Warsaw Pact militaries. G&G has taken a similar approach with their RK104, adding little details to this gun that raises the realism bar for all Airsoft gun makers.

Appearance

Like all of G&G’s guns, the RK104 is an attractive, well put together gun. Unlike G&G’s GR16 series, where the magnesium receivers make the GR16s feel deceptively light, the RK104 has a solid, weighty feel to it…as an AK should feel. The finishes applied to each part of the gun are well done and appear true to the real gun counterpart. What should be metal on the real gun is metal on the RK104. What should be plastic on the real gun is plastic on the RK104. The receiver exhibits very realistic looking riveting like the real gun receiver. The seams of the gas tube, rear sight block, and front sight post are authentic.

One quick note: the magazine supplied with the gun is patterned after a 5.45X39mm magazine. It looks great with the gun given its sleek, black styling. Purists will realize quickly that the AK-104 is the designation for the 7.62X39mm version. The proper name for the 5.45X39mm version is the AK-105. We were faced with a conundrum! Do we change magazines? Do we cross out the “104” on the box and scrawl in “105”? But hey, this is Airsoft, so we got over it.

The nicest detail on the gun is the bolt and charging handle. The G&G RK104 uses a bolt spring and fake bolt/gas piston that is wickedly similar to a real AK. Pulling and releasing this setup gives the bolt a heavy, chunky sound that will make real AK aficionados weep with joy. However, most airsofters who like to customize their guns will realize immediately that it will be impossible to modify the RK104 into a collapsible or no-stock variant. This gun is meant to remain a full stock weapon.

Not only does the bolt look real and have the realistic style spring guide. It pulls ALL the way back (just like the real one) and has a sturdier hop-up adjustment lever than the TM.

The selector switch is identical to the Marui with the cap covering the screw that removes the entire external selector lever. The lever feels much like the Marui: not too mushy and it clicks positively into place. The one we tested needed a little tightening, after which it felt more solid when clicking into place. Note that the selector lever will dig the “AK groove” into receiver…just like all the other AK variants.

One particular detail that should please realism nuts -- and disappoint the average airsofter -- is that the buttstock tangs are similar to the real gun. This means that you cannot use aftermarket stocks designed for use with the TM AK47. However, G&G made the buttstock longer than the traditional Airsoft/real AK stock in order to accommodate a 9.6V large sub-C battery. For most of us familiar with the traditional AK, this feels a little weird when shouldering the gun. But most airsofters will cherish the idea that we finally have an out-of-the-box AK that will store our beloved super-large 9.6V batteries without resorting to aftermarket parts or funky battery configurations.

Here’s a closeup of the sling loop on the stock. Unlike most TM guns, this sling loop is actually strong enough to take a sling!

Like the Classic Army SLR105 and most aftermarket stock sets, the stock butt plate is screwed on. Undo the two screws and the plate comes off to fit a large sub-C type battery. Don’t lose the screws!

Here is a close-up of the magazine well for the RK104. The shiny U-shaped piece in front of the hop-up unit is the rubber pad meant to prevent the magazine from wobbling in the magazine well. However, the result is that the magazine fit is very tight...almost too tight.

The RK104 has fully adjustable front and rear sights like the other AK AEG's on the market.

Before the RK104, the only way to get this level of external and cosmetic detail was to purchase a Guarder AK conversion kit for zillions of dollars. G&G has gone out of their way to make their RK104 as detailed as possible without spending zillions of dollars. However, the result is up to the buyer to decide if it is worth the extra money compared to a TM or CA AK AEG.

Performance

Given the market’s overall disappointment with G&G’s previous new gun releases, the RK104’s performance out of the box was a pleasant surprise. The gun fired smoothly with a nice, crisp report and no whining sounds whatsoever. The stock velocity ranged from 345 fps to 365 fps with a 0.20g BB. The gun fired roughly 600 rounds per minute with an 8.4v battery and was drawing 13amps. When using a 9.6v battery, the rate of fire jumped up to 700-800 rounds per minute and drew the same amount of amps. The gun sounded very clean and very intimidating when fired on full auto…similar to a TM AK Beita Spetsnaz when you fire that gun with its conical flash hider. The gun fired flawlessly with the included 600 round hicap magazine and worked perfectly with the Tokyo Marui hicap as well.

We’re concerned about the magazine fit: it was snug enough to require a hard push to seat properly in the magazine well. It took more than a little rocking and pressure to lock the magazine into the gun. This is due to the fact that there is a rubber pad inside the magazine well intended to prevent the magazine from wobbling like the TM AK. It sounds like a good idea, but the G&G hicap magazine that comes with the gun has a flimsy plastic lip. It seems like a matter of time before the user experiences feeding problems as the magazine is pushed away from the hop-up unit by the pressure of the rubber pad. We tried TM AK magazines, CA AK magazines, and Star 30 round AK mags in the gun, and they all fed equally well. We suggest getting some TM or CA metal lipped magazines to use with the RK104 for the long term.

Upgrading

The RK104 comes with what appears to be an M100 equivalent spring given its out-of-the-box velocity. We upgraded the RK104 with Area 1000 metal bushings and a Guarder SP120 spring. The gears in the gun were a bit loose, and required minor shim adjustments to get it to our satisfaction. Once the parts were installed, we noticed weak cylinder compression that was quickly remedied with a little silicone grease. After that, the compression was perfect.

We reassembled the gun and put it through the paces. The gun fired a tad bit over 400 fps with 0.20g BBs and only drew about 16 amps. The rate of fire was maintained at 700-800 rpm at 9.6V, and the report was much louder and more crisp. In both stock and upgraded form, the RK104 was a fun gun to shoot.

Again, we were very surprised at how easy the gun was to upgrade. The factory shim and lube work was somewhat disappointing, but compared to previous G&G guns, the RK104 actually behaved as expected after the upgrade. No surprises! No additional parts required! What a relief!

Disassembly

Now we will take you through a step by step disassembly of the RK104 and highlight the differences between this and the TM AK47.

The disassembly sequence is more like a real AK than a TM AK. First, remove the buttstock. Then, remove the upper receiver cover as you would a TM AK. This exposes the "real style" bolt, operating spring and spring guide. Remove the recoil spring and spring guide, and then pull the bolt rearwards in order to remove.

There are four main screws holding the rear sight block to the receiver, and unlike the TM AK, these screws are on the inside of the receiver to either side of the hop up unit. After removing these, the rear sight block and barrel detaches from the receiver, allowing you access to the gearbox. The hop-up unit is then removed the same way the same as all other AK AEGs.

Remove the pistol grip comes by removing the screw underneath. Then the upper and lower handguards come off just like the real gun. There is a small lever right under the gas tube and that will release the lower handguard.

Then the lever under the rear sight lifts up to unlock the upper handguard.

Once the lever is lifted, the upper hand guard pulls up and off.

Here you can see the Ver3 gearbox is identical to that of Tokyo Marui and Classic Army. G&G painted their version all black and has a black cylinder. The wires are braced against the mechbox along the top rib of the shell which makes installing it a breeze.

After opening the gearbox, we found the internals to look very clean…almost too clean. Break out the lube! A little lube on the gears and inside the cylinder made us much happier.

The G&G “R25K” high torque motor produces a decent rate of fire.

Conclusions

The G&G RK104 is probably their best AEG to date. We adore the attention paid to external cosmetic details. The gearbox is a faithful copy of the Marui version 3 gearbox. The gun looks good, and it shoots as well as a TM AK. We test fired more than 600 shots with it and it never had one problem. Nevertheless, our long term concerns center around the magazine fit and feeding.

Otherwise, we are impressed by what G&G has done with their newest creation. For those who are knowledgeable about or are simply fans of the real AK, this is definitely the one to buy.

Addendum:
We recently received an email from an AK aficianado and thought it
interesting enough to add to our review:

"I noticed a mistake in your review on the G&G RK-104:

One quick note: the magazine supplied with the gun is patterned after a
5.45X39mm magazine. It looks great with the gun given its sleek, black
styling. Purists will realize quickly that the AK-104 is the designation
for the 7.62X39mm version. The proper name for the 5.45X39mm version is the

AK-105. We were faced with a conundrum! Do we change magazines? Do we
cross out the "104" on the box and scrawl in "105"? But hey, this is
Airsoft, so we got over it.

This is actually incorrect. The magazine supplied with the RK-104 is the
magazine used in the AK-104. It is styled much like the modern 5.45X39mm
magazines, but has a curve more closely resembling the classic AK-47
magazine. Reference photos:

5.45X39mm magazine on AK-107
7.62X39mm on AK-103

Considering that the review could discourage "purist" buyers, I figured you
may want to know of its error."
