[Set] B&T APC 556 AEG Rifle Replica ETU - Black [ASG] + 210rd Polymer STRIKE MAG M4/AR15 Magazine [EMG]

Tested it out with my stock Arcturus AR-15 and can say that they feed well. They feel slightly heftier Blue box magazines but it shouldn't add any noticable weight to the loadout.

I would recommend these to anyone who wants to limit the number of magazines they carry but want to keep the same overall ammo capacity.

Fantastic mid-cap magazine. It feeds perfectly without any skipping, even during fast semi or full-auto shooting. The polymer construction feels very solid and rugged.

This mag was a gift to my gun. It works. Also it is fun how the mag spits out like a 150 bullets in a split second. It is a good choice if you're looking for a plus mag. Doesn't stuck to the weapon and comes out easily.

I've already reviewed the gun, but I've played with it a bit more. There's a few new issues, though I would not deduct points from then since they are fixable, and are nowhere near as bad as the issues some other "quirky" guns have.

Main point: magazine fitment. A lot of magazines just won't seat in easily or at all, while others are easily pulled out. Adding tape does not seem to significantly change the fit. Here's the mags I've tried:

DE 220rd midcaps - These come with the gun, but funny enough, they CAN slip out when pulled on. I would avoid using these, since I lost one of mine while playing.

Cyma Platinum 220rd Strike midcaps - These are advertised as fitting on the store page, but slip out very easily when pulled on, even more so than the DE midcaps. Avoid.

G&G polymer 120rd midcaps - Oddly enough, these *sort* of fit. They do not slip out, but they have to be rocked in and they also somehow directly put pressure against the magazine release button when seated. Not optimal but they work.

G&G steel hicap - Works fine. I assume most steel style mags also will work fine.

Specna Arms 125rd S-mags - These work perfectly. This would be my preferred mag to run with the gun. Sadly, the capacity is limited. Other similar style mags may also fit, but this gun is so weird about mags in general that I wouldn't bet on it.

Additionally, the magazine release button is a bit too easily pressed down on the left side (the ambi button), which leads to magazines slipping out if you have the gun slung to your side. I lost one of the DE mags this way. It may be necessary to DIY mod it to stop it from happening.

Also, the fire selector is in a bit of an awkward place, since it sometimes digs into my thumb when pointing down on semi, and occasionally switches to auto or safe because of it. It is likely moddable by changing or filing down the selector switch somehow, but for now I've left it as it is.

It's a well build replica with the correct trademarks.
The batterycompartment is somewhat limited: a 11.1 1000Mah lipo battery with deans connector is the maximum size I could fit. An AK-type lipo does not fit.

Furthermore, the hop-up is somewhat a let down; 0.25 grams bb's is the max weight to accomplish okay distance (40 mtrs max). So, outdoor skirms are somewhat linited with this replica.

I used this replica 4 times, both in CQB and open field games.

What I really liked:

+ It's a licensed replica with markings.
+ External build is decent, the replica looks and feels awesome. No wobbles, cracks and cheap feeling.
+ It's not another M4. Quite subjective but I've found this replica to be really good looking. At least 9 other players approached me to check it out, it's really an eye-catcher.
+ Not one, but two midcaps included. The magazines are decent.

What to look out for:

- The stock hopup bucking wasn't able to hop 0.28g BBs, resulting in ~ 10 meters range. This is not a big deal, just swap it with a preferred aftermarket one. This is generally true for most of the stock replicas, so just be prepared. I've seen some stock replicas being able to hop 0.28s out of the box though.

- The hopup chamber is proprietary. So no, you can't just use your favourite 100 euro CNC M4 chamber here without some tricks. The chamber looks like an M4 one with an elongated tube at the back. I've found no issues with the stock chamber. With an aftermarket bucking, it has a decent range, accuracy and consistency.



After trying this replica out, I've changed the hopup bucking and the spring. The quick-change spring system is indeed a quick one, not just in name. I've also removed the flash hider and stuffed some fitting O-rings between the outer and inner barrel, helping barrel stability.

With these minor tweaks, I've reached ~70 meters maximum range with ~60 meters effective range, measured with Google Earth.

The internals are similar to the Double Eagle M9xx series so pros and cons apply here as well. The 3.0 ETU comes with a pre-cocking feature, which helps with the trigger response time. Because the piston teeth rack is only partially metal, I have some reservations towards this. So far, I've had no issues with it.

I recommend turning the pre-cocking feature off after the game and pull the trigger a few times in semi. With this, you won't pack your replica way with a half-cocked piston.

The included midcap magazines are decent, modern looking. After disassembly, I've found a bit more silicone oil in them than absolutely necessary. I cleaned the excessive oil out. Both magazines feed reliably. If you need more, be sure to choose from the ones in the description or ask Taiwangun directly. It wouldn't take my old Cyma/Battleaxe magazines.

I'm using the Gens Ace 25C 1500mAh 3S1P 11.1V Airsoft LiPo Battery T-Plug, which fits just right. AK style batteries are too long for the battery compartment.

To summarize, this is a unique looking licensed replica with decent externals and internals. With some minor tweaks, I got a well performing unique looking replica. Would buy again.

Solid gun overall. Have played for 1 game and it performed well during it. I've only had a few issues with it, but those have been quite easily fixed, so I did not reduce the score for them.

+ Looks very cool and unique
+ Retractable stock works great with bulkier face protection
+ Externals feel very good with no wobble or bending anywhere
+ Stock MOSFET/ETU is quite good for the price point. Precocking in a stock gun is always nice
+ Seems quite accurate, at least after changing the hop up bucking/nub (so no issues with air seal, barrel fit, hop up unit and so on)
+ All the basic features like field strip, changing the battery and changing the spring work well
- Gears are a bit loud, but can presumably be fixed by shimming or by changing the gears at the latest
- Stock hop up is made for lighter BBs
- Magazine fit is picky

Extra info:

Stock hop up chamber and hop up bucking/nub can't really hop a .32g BB. I immediately swapped the stock bucking and nub out for a ML tensioner and Super Macaron. The dial of the hop up chamber only goes 180 degrees, so some hop is always applied for me now. I assume this can be fixed by replacing the entire chamber, or just the wheel/dial. The hop up unit seems like an M4 style, so I assume it can be replaced if needed.

The gun is also a bit picky about magazines. I was not able to get any G&G or A&K M4 magazines to fit. Stick to magazines listed to work in the product description if you want to ensure fit. The stock magazines that come with the gun are decent however, though they lack a follower.

Battery space is listed as AK-style, but the space there is only about 17cm long, so not all AK batteries fit. My basic stick style Titan battery fits in fine.

Very nice replica. Plastic parts feel very sturdy and the fitment of the parts is very good, very little rattle. It is a little picky with magazines, my PTS mags need some wiggling to lock in but thats my only complaint.

Got a bunch of these mags for my M4.
Very stylish.
Made of sturdy polymer.
Took them out to a game this weekend and they seem to be working perfectly.
The bottom plate seems to be easily removable for maintenance.

Top quality , very useful,best shop , good delivery time . Big variety of everything you need . I suggest it !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I got these for the capacity of 210 round, for use in a support gun. The quality is amazing and feels sturdy and well made.
The magazine has a funtion of lowering the capacity by a slide in the inner workings of the two parts of the magazine.
Highly recommend this for all M4 based players. Or for the support gunners using M240 models for its capacity.

the best magazines that I used ,fits most of m4 brands and feeds wery well ,I have tried the SA edge 1.0 and 2.0 also the H&K m416,modern design,and for 210 BBS per magazine and mid cap cant ask for more, I will buy them again for sure

I love these magazines.
They seem durable i really like the way they look.
They also have a red sign on the bottom so you may find them if you drop them.
They work really well with a bunch of M4s like my CM.105 Daniel Defense M4A1 Eshooter ETU - Black [EMG] and they fit well in every m4 pouch i tried so far.

Very good price/value choice.
Been to their first game with the new mags. Great performance, works really well as expected. Good design, good build quality, high midcap capacity.
Can recommend especially if is on sale.

The magazine is very nice, quality materials were used, it doesn't wobble, it dispenses excellently, it was a good purchase

It fits into every aeg I have tried except for the double eagle m904e.
I swear that this magazine feeds the best out of all m4 mags from taiwangun. Can handle 20+ rps easily and looks great!
The material is very durable

The magazine is of quality material and worked right out of the packaging without any issues. it fits my M916G and there is little to none wobbling while using. Please also note there are tiny red triangle element at the bottom if you are considering all black magazine.

Definitely one of the outstanding mag out there! Reliable, good looking, sturdy! The feed is perfect, there is no loose BBs upon taking out the mags from the guns! Fits perfectly with Specna Arms M4 replicas, but I guess it fits most of the M4 replicas! Easy to disassemble and maintain! Recommended!

So far, works great and a fraction of the price of EPM1 Mags. Good Build Quality.

I picked up 6 of them for use on my Wolverine MTW. That's 1,260 BBs ready on a HPA rifle

This magazine fits like a 100% original part. I use a m4 based replica and its also looking really good on it.

Even tho its polymer it feels verry solid and strong, filling it up without problems and its fully empty in seconds!

Working perfect on all type of mechanical configuration, not fit to all body for little large case construction.
Satisfy to all however.
Top service and shipping superfast!

Great value!

They fit perfectly in my Specna Arms rifle and even - unlike the mags included with the gun itself - these leak no BBs upon ejection!

They're super easy to take apart and fit in M4 mag pouches like a charm.

The fact that these hold so many rounds is astounding! Even less reloading required!

Overall it's a recommendation from me! They're well-priced, feel high-quality and have a great (very large) capacity for being a mid-capacity magazine.

When it first came out, I was skeptical about this mag.
Licensed, 200+BBs AND sub 20€ price.
Well, turns out, this magazine delivers on all fronts.
I looks good, has proper licensing, if you're into that sort of thing, it acctually takes 200+ BBs and feeds them to the last, no problems.
It's also fairly easy to disassemble for cleaning.
All this for less than 20€ makes this the best M4 midcap on the market, without having a PTS-price tag on it!

Great magazines, works perfectly. 210 bbs are really fitting and going out smoothly.
Never had an issues with them.
Currently using with HPA gun MTW by Wolverine Airsoft. Every BB flights out perfectly

The magazines are really good. I bought them at the suggestion of a friend of mine who prepares airsoft replicas.
Excellent capacity. They shoot to the last ball. Solid and reliable at a very competitive price. The spring is never hard and the pellets fit very well.
I can only recommend them

Did I find the best airsoft magazines by accident?
I can only give a complete conclusion to a limited extent at the moment.
So far 2 of the 4 magazines have been used (putting in more and more BBs so that the spring is accustomed to compression) and then shot empty.
But there are no feeding problems or jamming. All good so far!
How they do on June 10th at the next game day can be deduced quite well from this.
The important thing is that from the first to the 180th shot, all BBs reliably enter the hop-up chamber. In my test, they managed that flawlessly.
In general, I find it important to consider the price when buying airsoft magazines.
Cheaper alternatives offer beginners the chance to allocate their budget to other important equipment.
You can get four EMG Strike Industries magazines for just over 70€ with shipping. Whereas 4 EPM1 magazines cost 110€ more(!).
For the money you get a decent optic with mount, fancy attachments or even a used / cheap backup gun!
The Strike Industries magazines show that the durability of airsoft magazines does not necessarily depend on the price, but on the quality of the materials used and proper care.

So if you’re looking to buy a new set of high capacity mid caps, you can get pretty good magazines at for an even better price with these ones!

Quality mag, after initial break in it performed as expected on a balanced replica build, with no misfeeds.
The capacity is as advertised in my testing.
Used with DE m4 replicas and it fits quite snugly.

10/10 would recommend this magazine.
Its a cheaper version of the famous EPM1 mag, has arround the same capacity of them, being much cheaper.
Great build quality, was impressed by the material and design!
