i have owned, DPMS, Armalite, Oly Arms, and will be ordering a rockriver arms in the next month or so. For the money you can get a DPMS or OLYarms for around 700-150dollars. The armalite i owned was CRAP everybullet i put threw it jamed. My friend has a bushmaster and it is a nice gun ($1000), BUT personally i think the RRA is going to be a awesome rifle. I see them blazin at the range all the time. I am gettin myne for $897 i think and +10% for FFL shiping
