I have a new build. It is a superior lower and a Blackstone upper. This is my second build and I have run into problems. I load mag with good ammo(USA AND HANSEN) and they get stuck after they fire. The noise is not right so I do not think they were seating properly when fired. They get stuck in the chamber and so does the bolt. When I first started trying the bolt would close somewhat but when I pulled the trigger it clicked. Upon examining the brass it was a faint dent where the pin had engaged but not enough to fire. I notived that I had a blown case that was about a 1/4" above the base. Could this be head spacing problems. Seeing as I am using good ammo that cant be it. Since the ammo is not seating could it be mag. I lubed the bolt alot before I began, but it could not be enough. I'LL stop now. Any help would be appreciated. [/size=4][/size=6][/size=1] |

Thanks for the tip. I deserve the flaming. I have made that mistake more than once but really know better. I shot IPSC for 4 years.

When you say "Blackstone" upper, did you really mean "Blackthorne". If that's the case then that's more than likely your problem. They tend to suck at anything they build. They've changed their company name a few times because tehy continue to gain a reputation quickly for making crap. If you had a case rupture above the case head then the chamber dimensions and headspacing are probably off and the rifle is not safe to shoot.
You can contact them and see if they'll fix it or replace it since it is a safety issue and they could get sued for selling an improperly headspaced rifle that is just waiting to KB on you. Good luck though as Blackthorne only warranties their products for 72 or 96 hours (Something crazy like that). I hope you get it worked out. |
