Matrix 120rd Metal M4 / M16 Mid Capacity Magazine - Set of 5

24 Customer Reviews

"So I bought 7 of these mags a few months ago as extra magazines and also to replace the crappy ones that I initially received with my first gun, and I was a little worried about the black "lip" that they have on the top of the magazine where the bullets would go in IRL. Thankfully, I have had no trouble with getting these magazines in/out of my rifle, and I didn't have to do any modifications on the magazines or the rifle itself. (I have a full-metal DBOYS M4 AEG from a different website.)
I tested out the capacity on one of the mags by loading it and unloading it 3 times in a row, and the results were that it held 123 the first time, 116 the second, and 101 the third time. I've heard that it's not good to fully load your magazines or keep them full for extended periods of time as it can damage the spring and I really hope that wasn't what was going on with the decreasing numbers...
Anyway, after that I loaded the other 6 magazines up once each and they held 91, 101, 115, 114, 94, and 112 rounds each. That averages out to a little under 110 bbs per magazine, which I think is more than enough considering the real thing only holds 30 5.56 NATO/.223 rounds, even though these airsoft versions are advertised to hold 120bbs.
Another 'test' that I performed on these was to find out if it had a realistic weight. I didn't actually have a scale on hand when I performed the test, so I just estimated by how they felt in my hands. I took a real AR-15 magazine as well as one of these airsoft magazines and proceeded to load/unload them for each part. I found that when both magazines were unloaded the airsoft mag felt a little bit heavier, but when they were both loaded the airsoft one was a little bit lighter. Go figure.
I initially bought these magazines because they are metal and gray in color like the real steel ones, instead of a matte black like most airsoft m4/m16 mags are. However, these mags do have a black "lip" like I stated earlier, but that doesn't really matter because they're going to be inside your gun or your pouches anyway. The paint scratches and rubs off on other metal surfaces like your mag well after extended use, but I think that just gives them character and adds to the realism anyway.
They have a rough texture to them which surprised me a little when I first got the mags. I really had to stuff them into my mag pouch to get 2 of them to fit in each pocket and yank on them while working the magazine side-to-side in the pockets to get them out at first, (I have the Triple M4 / G36 MOLLE Ready Magazine Pouch by Condor / Phantom - Tan pouch from this site by the way), but after leaving them in the pouch for a week or two and periodically working them out of the pouch and putting them back in at different angles to stretch it out, they fit alright now. The problem was probably caused by a combination of the texture of the magazines that made them sort of grip each other, the lips on the mags stretching the pouch more, and the already tight pockets of the pouch.
I've dropped these things a few times and they took it like a champ, they barely wobble at all in the mag well to a point where it doesn't even matter, and they all feed efficiently too.

Durable METAL
Extremely minimal wobble
Feeds well
Mostly realistic appearance and weight
Sufficient capacity
Excellent performance for the price
Paint rubs/scratches (can be a con)

Paint rubs/scratches (can be a pro)

Sorry for the long review, but I wanted to make sure that I put down every detail that I could think of. All in all, if you're looking for a good quality magazine that's not going to break the bank, this is the one to buy.

"I got these magazines a few mouths ago and I love them I have played a lot of cqc games and dropped them allot. They can take a beating. Never had a feed problem I run these with my vfc h&k 416 and there amazing

"Guys, if your gun takes STANAG magazines, then these WILL work. The only exception is the G&G FN2000, which the mags needed to be slightly modified.
by Richard C. on 01/23/2011
"These are fantastic mid-caps. They feed well, and the full metal shell is smooth with no rough edges. They don't wobble in the reciever, but they still slide out on there own when you hit the mag release (on a metal bodied Matrix Tactical at least). Overall, I am very satisfied with these mags, and would recommend them.
by Jake K. on 01/14/2011
"this mag is great and to my conclusion it actualy hold a little more than it says matrix never falls short in thier products and these are probly the best mags outthere escpecialy for the price

"I was wondering if anyone could tell me if these are compatible with the jg m4 "tank" assault pistol? Thanks for the help, any help or info is appreciated..

"These are excellent. I own a VFC M4ES 145R and these things fit better than the $20 per magazines that are available for my gun. They are very durable and fit better and feed better than the standard magazines for my gun and the paint doesn't scratch like the other ones I will most likely be buying more of these in the future.


Excellent Fitting
Excellent Loading
Very Affordable
Very well made and you can't beat the price!
More realistic
Silent (All mid-caps are)
Better than the more expensive ones)

I would recommend using silicone oil when you first get them to work them in a little and they might double feed at first but after a couple reloads and unloads they will work fine again. This isn't really a con but a recommendation.

I would defiantly recommend this product to anyone that has a gun that this will fin in including the above in the description and any VFC M4 E-series gun.

"Overall these mags are great, good feeding, tight fit with no wobble at all. Only problem I had with them was that they dont fit in the Jin Jong S-System without some slight modding. Any gun with a metal mag catch will probly have a problem with them not locking in do to the fact the mag catch is bigger so you have to take off the shell and file it where the catch slots in. Other than that like I said great mags!

Tight fit
Realistic fit and feel
Decent capacity

Some modding required at times
Not actually the right color

That last one is personal prefference for me, real m4/m16 mags are more grey than black but not really that big a deal.

"Matrix Metal M4 / M16 68rd No Winding Mid-cap Magazine. (Box Set of 10)

First Impressions: Upon opening my package, I was surprised to find that all ten magazines were individually packaged. When I opened the packages I examined the finish on the magazines. No blemishes, no paint that can be scratched with a fingernail, nothing out of the ordinary. Nothing but a flat black finish, and a nice one I might add.

Testing: After examining the externals, it was time to load them up and try them out. Before loading them, i sprayed silicon oil into the feeding port of all of the magazines (recommended) to ensure proper feeding. I filled all of the magazines with MATRIX .25 gram BBs. The first time I inserted a magazine into my gun (G&G M4) I noticed that the color of the mags matched the finish of my gun, which is a deep flat black. They looked nice, but how did they feed? Well, it was time to find out. I Took my gun into my backyard and immediately started firing, first semi-auto, then full-auto. I did not notice any double feeding or dry firing. No, just precision feeding, just like the description says.

Feed flawlessly in a G&G M4
Nice finish.

Only 68 rounds.

Conclusion: These magazines are the absolute best you can get for the money. they're $10 a piece, but when you buy a ten pack for $60, your only paying six dollars each, what a great deal! That's even cheaper then MAG midcaps, which are plastic. They feed great, look great, and the price is great! Even the shipping was great too, it took less than a week to come from california to virginia. Overall, i highly recommend these magazines to anyone who has an M4 or M16, beginner or professional!

"These magazines are great for realistic game play. They tended not to load well, a couple of drops of lube and they are flawless. They work great in my d/boyi scar, and there's nothing like knowing you have all the ammo you need to make your shots count.
by Hunter M. on 04/13/2009
"Great mags for the price. Had them for about a week and have used them a lot and have had no mis-feeds or jams with them. Each of them come in their own little package so don't freak out when you see them not all in one box. full metal except the top part where it is inserted into the mag well. The only bad thing i found is they do scratch pretty easy, no big deal for me, but then again i don't know you. great learning ammo conservation and are strong too for when you need to change mags quickly and they fall onto the ground. Great buy, would recommend to everyone!
by Robinson A. on 02/17/2009
"i got the kwa m4 cqb n these mags work great all of them fit and they feed really well. if u like holdin the trigger these aint the ones u wana get they go pretty fast especially when u use a lipo, but overall great mags.

"yes, these are compatable with Tokyo Marui, ICS, Classic Army, G&G, G&P, Echo 1, Matrix, BoyI and other compatible M4 / M16 / FN2000 / L85 / SCAR. it says right in the description ;)
by gfd g. on 10/29/2008
"do these mags fit the Army L85A1? if not which mags are best that fit the Army L85A1?
by Sean S. on 08/19/2008
"I ordered these for the ICS M4. I have no trouble with compatibility, they all fit like a glove with very little wiggling. I alleviated the small bit anyway with electrical tape (I'm very anal about the solidity of my rifle). They feed flawlessly, and feel right because they're made of metal. I only had one problem with one mag "breaking": the little tab broke on the inside, unleashing the plastic innards (all intact, the metal is just a shell). I fixed this easily, as I was taping all of the mags the same way anyway, now I cant tell which one it was. Great value for a great set of magazines, I would definitely recommend them over most, especially at this price!
