Initially I confronted...
Initially I confronted problems with the rifle jamming, replace the extractor with mil spec one from Brownells and the rifle worked flawlessly. It is very accurate and digest all kind of .223 and 5.56mm ammo. This rifle comes with a 5.56mm NATO chambering. It is a great rifle for its price.

Can't say enough good...
Can't say enough good stuff about this Olympic Arms Carbine. Looks badass and shoots awesome. I ran all kinds of ammo through it this weekend, from cheap stuff, tactical tracers, to some mil-spec NATO rounds and it chewed it all up like candy. I love these AR's . Quality much better then those bushmaster things everyone seems to love. Probably because Oly Arms makes every single piece in-house. Thanks Bud's for the awesome price (cheaper then I could get from the factory that I live by!) and for the layaway plan that I love so much! A++++

Great gun, great...
Great gun, great price. Not one hiccup using brass. I bought a case of the cheap-o Tula russian stuff that everyone warned me about and it jammed like a roller derby girl. I live 100 miles from Olympic Arms in Washington and had to order from Buds to get a price this low....
