I built a garbage grade .300 blk pistol. Today I went to test fire it and in the first 15 rounds I had two primers blow out so I stopped shooting it. (Primers came all the way out of the case)
It is a pistol length .300 with a 7.5" barrel. I was shooting armscor 147gr.
I haven't ever dealt with this before. Not really sure what I should do about it. I was thinking about tossing a complete BCG from a different rifle in it to see if that fixes the issue. Or should I leave the gun alone and try some higher quality ammo first? Or just take off the upper and throw it away?
All of the upper parts are from bear creek arsenal. The QC on assembly was terrible. All of the bolts on the handgaurd and gas block we're finger tight and the gas key had not been staked. I completely disassembled the whole thing and put it back together with things like tools and locktite before I even tried it.
I would like to be able to run the wolf .300 thru this thing when it hits the shelves but these blown out primers made me a little nervous.
Thanks.
