I started having a malfunction with my M1A today at the range.
It first started when I chambered a round a got a click instead of a bang. I figured I didn't seat my magazine correctly and the bolt just hadn't stripped a round from the magazine.
I pulled the bolt back and there was a round in the chamber, it just had not seated itself under the extractor. The extractor was holding the bolt back slightly so the firing pin could not hit the primer.
I removed the magazine and worked the bolt with the round chambered. I then replaced the magazine and the rifle fired and fed the next rounds OK. I ran a 20 round mag through the rifle no problem.
I then moved to a 200yd range. Then I had the same problem. There were a few other shooters around and I didn't feel like fiddling at the range so I went home. I stripped the rifle cleaned the chamber and barrel and cleaned the front of the bolt and under the extractor. Not real dirty. Then I added a mag and tried to chamber a round and got this-(pic)
It seems like either the bolt is getting slowed down enough to not seat the cartridge under the extractor (or just stopped like in the pic). I tried 2 mags, both do it, neither did before. I bought the rifle used but I have had a few hundred round through it with no issues.
With the bolt out and I can seat a cartridge under the extractor.
Any common answers? Could the mag feed lips just be hitting the bolt? I tried to look for this but did not see it. With an empty mag it's hard to see if there is interference due to the bolt hold open. Any advice?
