RA-Tech Steel Bolt Stop for WE M4 Series Airsoft GBB Rifles

"amazing piece you should get. hasnt failed me yet!

"I grabbed this part because my bolt would never catch after converting my WE M4 to the "OPEN BOLT" system. after installation, it worked immediately. Hghly recommend for anyone having an issue with their bolt not catching.

"Everything is cool, but the tooth that catches the bolt carrier is too low. Should be few milimeters higher to hold it more confident.

"Nice, solid boltcatch, however the tooth is few milimeters too low and sometimes releases bolt carrier, and stays on the other side, which causes damage.

"These bolt stops deform very quickly under normal use especially with the RA-TECH steel bolt carriers. They are not worth it. RA TECH claim that their steel bolt stops and carriers are heat treated for hardness is misleading. The steel bolt carrier does do better than the we tech m4 zine alloy bolt carrier but it and its companion bolt stop do not hold up under use.
