Got something I know nothing about, but want to know if any of ya'll do. I have a customer that came in today that's built an AR15 from a kit, purchased from a company called Blackthorn out of maybe Minnesota, (the customer thinks??) He has already returned the upper receiver twice, and is now on #3, (which is doing the same as the first 2) after about 140-150 rounds, the casing completely jams, and he has to use a ramrod to beat it out from the muzzle. On the case that jams, the "Extractor Groove", (where the claw grabs it), is broken. The force of the "extracting action" snaps it almost completely off. He has used several different brands of ammunition. None of it is the high quality ammo, and not all of it is reloads either. Any suggestions?? And more of the reason for this, Anyone heard anything about "Blackthorn"??
