I have an Adams Arms midlength 16 inch with a Rock River lower and DPMS lower parts kit.
It was real hard to pull the bolt to the rear. I think it was the pressure of the hammer on the under side of the carrier. I put a lot of CLP on it At the range, repeated malfunctions. The shell would eject then the bolt would not have enough momentum to chamber the next round. Near the end, it was happening much less frequently. But still hard to pull the bolt back, but better than it was. Is this common? and will it get better? Or could I get a new hammer spring if that is the Problem? |
| Does it feel like a physical obstruction? The tail end of the AA bolt is a little larger than the standard bolt carrier. I've heard some people having similar issues fixed it by locking the bolt to the rear and loosening the stock nut then retightening. Supposedly it should align the tube to the bolt better. |

When you pull back the charging handle you should have some resistance - more so when you are initially cocking the hammer but not difficulty. I am not an expert but when the hammer is cocked it should have little contact with the underside of the bolt - when the sear has it enaged. As far as CLP - anymore than a drop is alot for that specific area My best advice would be to find an ARFCOM member in your area and have them look it over.. |
