My "Christmas Rifle 2009" Ruger Mini-14 581-series is accurate enough for me (2 moa at 100 yards w/Weaver K25 scope). I can always blame my old eyes. It functions every...single...time I pull the trigger. And, it looks like a rifle.
I'm not unfamiliar with AR's, but the low-priced versions usually need something before they'll work...like sights. And it seems like no one can resist hanging the doggonedest things off of them. My brother, for instance, put the 5-position collapsible stock, a monolithic Picatinney rail hand guard that free-floats the barrel of his HBAR, a flashlight, a green laser, a bipod, and a scope that mounts on the carrying handle. That sucker's heavy.

PS. I got mine at Wal*Mart for $607.00, well under the MSRP, and the last time I looked, just last week, they were still $607.00.
