Always been real impressed with Armalites, though they seem to have trouble feeding steel cased ammo. Other than that though, the ones I've seen have been stone cold reliable over thousands of rounds and quite accurate.
I've heard that too, BR. Something about tight chambers I think but I've heard ArmaLite has resolved that issue and issues with 5.56. Anyway my 2009 ArmaLite has a loose chamber and loves steel case and 5.56. RedneckFur, this might be a good test for your new rifle!
