| This past weekend i built a Rock River lower and i mated it to a DPMS upper...its a damn tight fit, but the colors are off..Anyway I have an extera spring left over/...I know can't be goos...it about an inch long and it coiled really tight...My problem is when i fire the weapon the bolt comes back but onlys goes forward about half way when it cycles the round...You can manualy action the bolt fine...just when you fire it it stops half way...My thoughts might be that the bolt is some how catching on the hammer: because it doesn't reset itself...This is my first build and i would appreciate any advice. |

There is the takedown detent spring that goes into the back of the receiver and is held in by the stock plate. And there is the safety/selector spring that goes up from below, just before you put the pistol grip on.  look here for help |

What is the spring closest to on the list, and how does it differ? Is it longer/shorter/smaller diameter? Is your bolt carrier gas key catching on the gas tube when the carrier goes forward? It might just be tight? Are all parts new? Mine did that when new. A little shooting fixed it. |
