I am not really an AR fan but from my limited experience Rock River Arms makes as good as any for the money. I bought an ATH (Advanced Tactical Hunter) some years ago that shoots Federal or Winchester ammo loaded with 69 grain SMK into 1/4" groups at 100 yards. Needless to say I was pleasantly surprised and my friends who had some "top of line" ARs that cost 2-3 times as much were livid that they could not get that kind of performance. I really thought it was just a fluke and I had gotten lucky in the purchase. When my police officer son-in-law needed an AR to carry in his patrol car, I was more than happy to give him my ATH. A year or so ago I decided to try another ATH and lo and behold it shoots the same ammo just as well as my last. The ATH is either one heck of a gun for the money or I got lucky twice
