Avengers Polymer Magazine for M4/M16 Series Airsoft AEG Rifles
(Color: Black / 370rd High-Cap)

"These fit and work for my VFC Avalon. They feed well, easy to load, I've used them for about 3~ months thus far. Still in really good condition and doesn't show any signs of breaking just yet. Mind you, I have been taking care of them and not just carelessly thrown them around in the dirt. If you take care of your mags, they'll take care of you.

"These mags are very good. I bought the Black 150 model mid cap ones and they are amazing. The only thing is that the top of the mag is clear in the images but the real ones are also solid black on the tops. That’s not really a problem for me thought and they are some amazing mags. I did not get any damaged ones and I bought 5 so if your looking to buy some i would say your not going to get broken ones. I love them

"Bought this mags for my Matrix MK18 build and got the grey mags. ordered black but the grey look really good with the grey dust cover and little trim pieces. but these mags hold right around 150+ some will load up to 155-163 bbs. this mags fit all of my M4s except for my sons Cyma m4 CQB. the feeder doesnt line up with the hopup tube.
