Greetings All,
I am experiencing an extraction issue on a .308, that I think I have narrowed down to the extractor. I am new to diagnosing problems (and building custom rifles), so forgive any ignorance on my part. The cartridge fails to eject from the breach. Everything works, cycles and feels fine, but more often than not, the cartridge is left in the barrel and the .308 tries to load another. After the bolt is removed, dropping a cleaning rod in from the muzzle, easily dislodges the stuck cartridge. This is a new Aero Precision rifle, 16" barrel with muzzle brake/compensator and an unbranded bolt carrier group. The BCG was a left over Mil-Spec unit from an upgrade; new, never used. I can post pictures as soon as the extractor is removed. The bolt was very tight in the carrier, so I installed a spare JP Rifles one piece gas ring. The bolt now moves freely and I am going to take a look at the extractor. Is there anything in particular that I should be looking for, that can identify the extractor as good or bad? If I had a bunch of $$$ I would simply buy a JP Rifles bolt and solve the problem.
Yours,
Manic Mike
