DPMS and Rock River Arms AR's; Tackdrivers. These rifles will out shoot most bolt actions. I have a DPMS LR .308. I special ordered it with an optional JP adjustable trigger, stainless fluted bbl, and dust cover. I also have a Rock River Arms .223 Varmint EOP 24"with a Stainless bbl, and it is also top notch quality. When I bought my RRA, they didn't offer a .308, but they do now. No experience with any others, but anything these 2 companies put out, I would buy again. Lindys Guns in Boone turned me onto to these 2 companies, as lots of cops buy them, and he is their dealer, and mine too. Great guy to deal with.
