| Yesterday i finished with my pistol build.When i was at the range today,the first two mags ran through the pistol perfect.The next mag shot the first round,but would not eject the spent brass.I had to do this manually everytime.Any ideas what the problem is?I used a PSA lower and lower parts kit,REDX ARMS 7.5 pistol upper, PHASE 5 complete buffer tube assembly and a ROCK RIVER bolt carrier group thanks |

Ran perfect for 2 mags then started to choke.... time to check if the bolt carrier group locks back after the last round in the mag, every time. If not it is short stroking and you got yourself a leak, what kind of ammo?
You should check your gas block for sure, but you need to check the Key on the bcg Lube it, put on #60 O-ring on the extractor. Check extractor hook to see if it chipped/broke. Try a H or H2 buffer to slow things down a bit. |
