This high quality mid-cap magazine by G&G holds 120 rounds and feeds flawlessly in G&G AEGs capable of accepting a M4 style magazine. Also feeds in most other TM compatible M4 AEGs. This magazine has a special follower that allows even the very last few BBs to feed into your AEG. The magazine is textured for a secure grip.
The mid cap magazine is made out of plastic , unlike the regular high cap magazines. My mid cap wouldn’t feed right and after a few times of using it the plastic snapped. Stick to high cap magazines if your looking for something durable.
