Quickly troubleshoot a malfunctioning KWA M1911 Pistol in this KWA Maintenance Minute video from KWA USA... "If you own a KWA M1911 and the pistol doesn't fire, you may be missing your firing pin. Watch this video to check for a lost firing pin and to reinstall a replacement."

New video submitted by RA-Tech as they feature their M4 bolt for the KJ Works M4 Gas Blowback rifle which looks even more realistic than the original. The next part of the video is a custom M40 rifle which comes with woodkit and upgraded internals. Also in this video is their CNC'd steel firing pin and hammer for the WE AK74 gas blowback rifle.
