Reviews & Ratings for Rock River Arms Left Handed RRAGE .223/5.56mm Completed Upper — 1 review — Page 1

Who ever designed this clearly never shot it. They mirrored a standard upper not taking into consideration the fact that the dust cover, that opens DOWN, sits right behind the bolt catch. This means when installed on the vast majority of lowers it puts pressure on the catch preventing you from cycling the rifle. You have to either strip down the upper and remove the door, or modify the lower to allow you to use this. Horrible design flaw.
