16" dpms preban rifle with 6 position stock no internal mods except newer gas rings.
Well here's the problem did the best cleaning I've ever done (since the corps) and
she'll eat the first 2 to 3 mags of ammo then proceed to fail to eject and extract...
leading to several comments about this so and so and that so and so....well then
after a field cleaning best possible on site, i'll get 10 to 15 rounds then the same
thing!!!!!!!! Help this is my only long gun to keep the Zombie hoards away.hasStill a big problem........

this sounds like the same kind of problems i was having.

and i started out w/some prvi partisan and remington green box, then went to wolf.

funny thing is i threw some lube in there on the extractor and near the end of the 400 rds i was able to run 4 mags through it w/o a hiccup. but that day i probably had no less than 30 fte/ftfs

Hey guys, I have recently built my second AR15. I had my first failure to extract yesterday and the resulting jam was the worst firearm experience I've had so far.

It's a Del-ton 16" middy A2. I am using Center Industries "USGI" magazines. I was shooting 55gr FMJ Wolf military classic ammo. I have put about 140~ such rounds through this gun. I have cleaned with brake degreaser and Remington CLP.

I was told at the shop that I probably haven't cleaned the chamber with a chamber brush. I think that is most likely the problem. However, does this mean my gun can't fire more than 100 rounds of Wolf reliably???

Do you lube after cleaning?  Soak it with CLP and try it again...
