I went to the range today with my new RRA upper. My setup is RRA upper /bolt/9mm hammer. DSA lower. hann block.uzi mags. Wolf ammo. The rifle shot great. Big smile on my face. shot about 250 rds. I had a few rounds from the last box. loaded the last mag. Fired 9-10 rounds CLICK. thinking that was it for the mag... Pulled the charging handle tilted the rifle to check the pipe, BOOM! I had two rounds cookoff the one on the bolt head and the next one in the mag. Thank you shooting glasses! I'm ok but . WOW At first I was thinking it was a hang fire. But now I'm not so sure. after cleaning up the rifle. I noticed that the hammer will drop even if the bolt is not fully forword. It has about one inch of bolt travel that will allow the hammer to fall. is that normal? This is my first 9mm AR. any help you guys could give? Sorry this was for the pistol/cal AR forum |
Yes, that's normal, but firing out of battery isn't. Sounds like a hang fire to me. That's why they say to keep the muzzle down range and wait a few seconds after a round doesn't fire. People here will be quick to blame Wolf here, but I've seen it happen with Winchester 9mm. Fellow arfcommer had a round fail to fire in his G19, lowered the gun, and it fired as he was reaching for the slide. |
| 9mm ar's are dirty guns due to their blowback design. Most will fire out of battery, but that should never happen if the gun is running right. Keep the gun clean, and clean it often, this will prevent the round from not going into battery due to GSR, gunk and grease holding the round slightly out of battery while firing, use less lube than usual because the blowback gas and burnt gunk will turn clean lube into tree sap in a hurry. Keep on eye on the bolt/carrier/chamber after a few hundred rounds, you don't want it to get to the point of getting sticky, thats when you run the chance of the round not going into full battery and blowing out the back of the case. |
