My friend and I went shooting tuesday, and took a new shooter. He had a blast.
Anyway, my friend's AR (purchased new on Sept 14th) was having some problems.
The first time we shot it, we went through 100 rounds with no problems whatsoever.
This time, the first 30 rounds went perfectly, but then on the next mag it was having failures to extract (causing a "double feed" situation) about 70% of the time. I took his rifle apart and fiddled with the bolt and carrier, and then the next mag went through just fine.
Again, though, after that, it was pretty consistently refusing to extract the fired case. I thought it might just need more lube in the bolt/carrier.
After we finished shooting (our trusty Hi Powers never bobbled ) we went to his house and took the bolt apart for a good cleaning and lubing. We also consulted the USMC M-16 handbook.
The whole thing wasn't very dirty, but I cleaned and lubed it up anyway. The handbook said to check the condition of the extractor and it's spring, and it was just fine.
I got an email from him saying that he tried it again yesterday, and although it did better, he's still having failures to extract.
I don't know what to think... he bought a case of .223 at the gunshow, and that's all we had been shooting when we were having the problems. However, I still don't understand the problem with the intermittent nature of the problem. For a while it's fine, then it will jam consistently. BTW, it wasn't magazine related, we used five or six different 30-rounders.
I would appreciate any help you could give me (and him) for this.
Thanks,
Wes
