Evike.com BAMF 190rd Polymer Mid-Cap Magazine for M4 / M16 Series Airsoft AEG Rifles (Color: Black / Single Magazine)

"I bought these mags when they first came out and let's just say they are picky on what M4 you use. They don't work in my Ares amoeba, or in my matrix commando, they feed intermittently in my cyma m16a3, all my Elite Force m4s and the only M4 that's had no issues with these mags is my cheap dytac sbr, and my sons force tac m4a1.
The mags have a really good quality feel and do feed until the very last 4 or 5 bbs and at the time these were the highest count mid cap. I would only buy 1 maverick next time and test fit it in all my m4s before buying 10 of them.
The linex 200 round mid caps work in all the other m4s above except for my sons Dytac, Force Tac, and his elite force m4a1.
Overall very good mags and they do take a beating, a mixture of me and my boy dropping these doing mag flips on concrete and having 2 of them slide off the roof of our barn and still work is incredible!!!

"To be completely honest, you are getting what you pay for. I got the tan pack of 5, they are light and made of plastic, don't feel very sturdy, and two of the five wont even properly click into my magwell. If you are looking for a cheap bargain, go for these, but if you are looking for good, high quality mags, spend the extra money and buy PTS mags.

"It gives me feeding issues in my umbrella armory m4.

"They are good mags, good quality, just on some guns when you put the mags in, they immediately fall out of the gun and it takes a few tries to get them to stay in the gun.

"Does not work in the G&G CM16.

"These magazines initially didn't "fit" into my lancer tactical m4, meaning they wouldn't like click in place and start feeding.
I know lancer bad lol but shut up nobody cares about your krytac
The fix for this was pretty simple, I opened the thing up and took out the little nub that holds the bbs back and sanded it down, (you can prob find a guide for this online) then it worked fine, other then that these are good mags

"Love the mags, they feed very well. The only problem is I was able to completely pull them out of my G&P aeg without too much force. They stay in while running but if you give it a tug it will come right out.

"The compatibility description is false, Gen1 BAMFs aren't compatible with G&Gs.

"Mags feed great and fire great. However I haven’t been able to get more than about thirty rounds in the magazine. I’m pretty sure I’m not doing anything wrong while losing them I’m using a speed loader but I can still only get thirty rounds in.

"I purchased the 5 pack. I have a Laner Tactical Gen 2, the keymod one and the mags did not fit however with a slight modification they were able to fit. If you trim down the top of the square on the side it will click into place. I test fired one and it did feed well on semi auto however had a few blank fires on full auto. The mags are plastic, but feel okay.

Just beware if you have a lancer tactical Gen 2.

"Bought three of them for my M4 AEGs. 1 out of 3 fit perfectly and the rest really need to be jammed and jimmied in there. Don't know if it's bad quality control or something else, but it's disappointing. They seem like good mags otherwise.

"Tried putting it in a matrix m4, doesn't hold in correctly unless smashed into the gun. Tried two guns, and doesn't work in either M4s, I can get it to fit but it will not feed at all. Might update review if it works eventually.

"Expect trouble, with a simple fix
The latch that holds the BBs in does not have enough of a ramp to work out of the box with some guns. It wouldn't seat in the rifle, and once jammed in it wouldn't spring back to let BBs load.
Had to use a soldering iron to melt and reshape the ramp - if it weren't for that it would be 5 stars. Great product with one annoying flaw, honestly will order more and keep the soldering iron handy

"So, I got a total of 11 of these mags, and finally got to test them this weekend. The capacity is amazing, and they feed spectacularly thru my rifle (ASGI Custom Talon, with a G&G Raider base). The only flaws I see in them so far is they feel a little flimsy, but so far they've held up well. The people around me said they liked the size, but they all said the ones they had broke, so I'm still mixed on this one. I will update this review if/when I put these mags thru their paces harder and have any further information

"I didn't realize these are significantly longer than a standard 30rd. mag so I can no longer use my authentic grip pod with it. These make it so I can't get any sort of elevation and I cannot simply set it down on the bipod and let it sit out of the dirt, it will fall over. Also the window in the side that shows false bullets is absolutely disgusting looking, it's paper behind it and even at a distance doesn't look even remotely real it just looks trashy.

That said these really hold a ton of bbs for a midcap and I have yet to have a feeding issue or loading issue and they are quite solid.

TL,DR: Mags are LONG and ugly but hold a ton of bbs and work flawlessly with my gun.
