All Operator 2 rifles feature flat-top receivers and 16-inch chrome moly 1:9″ twist barrels with 5.56 NATO chambers, tipped with the RRA Tactical Muzzle Brake. I purchased the Rock River Arms AR-15 AR15 Model BB2522 Rock River Arms Operator 2. I found the BB2522 Operator was the most unusual-looking member of the group with its gas system and a unique Free Float hand guard.
Listed here are the specific features as shipped through my online dealer.
