"Bought this for my Cybergun Microswitch M4*. The King Arms catch is significantly bigger than the Cybergun’s but it just barely fits into the frame and works perfectly fine.

Thanks! I think this will work on most AEG M4s.

"I don’t have a King Arms M4, but I purchased this for my matrix Sportsline M4. The bolt catch broke on mine so I bought this to replace it. It’s significantly bigger and thicker but it works so I’m satisfied.

I’m pretty sure this will work on most other M4 AEGs with bolt catches

"Works great on my Kingarms m4 it's the Evike Custom scorpion Edition to be specific. And it's a fuctional release on my gun so if it is on yours make sure you push down the little black piece on the right side of the reciever when installing the bolt release.
