King Arms Steel Bolt Catch Set Set for WA / G&P / King Arms M4 Airsoft GBB Gas Blowback Rifles

1 Customer Review

"This part is a whole lot better than the OEM one on the AGM GBB M4; which is what I replaced it with.

It works flawlessly, but the bolt catch is a stronger metal than the bolt was, and the bolt where it catches the bolt-catch actually rounded off and now the bolt doesn't lock back when the magazine is empty. Was going to get a steel bolt anyway.

-better metal
-better springs so it doesn't flop around when firing and locks back the bolt on a magazine that still has bb's in it

- Need to upgrade your bolt to one that uses stronger metal. Preferably steel since the bolt catch is steel.
- Had to shave some of the metal off the side of the bolt-catch housing to fit in my AGM GBB M4. Though this shouldn't be a problem with higher-end GBB M4's.

All around a good replacement/upgrade part.
