Rob- O's Review of Rock River Arms A4 .450 Bushmaster Completed Upper
Bought 2 uppers and neither of them cycled so I sent them back and got 2 new Uppers and now they are still doing the same thing. Rounds don't eject and bolt doesn't stay open once mag is empty. I am returning these items because it seems like the quality assurance is not there. I was really hoping for a plug and play product, but I guess not.
