This is a Brand NEW ROCK RIVER ARMS upper custom built by Pete in NH. The upper has been test fired and is perfect in every way. The upper is a flat top RRA, the BBL is Chrome Moly Steel 16 inch with an A2 flash hider pressed on the front. The upper is complete and test fired by the person who built this for me, Peter at Legal Transfers. I paid much more for this, but I am letting it go for less because I have a new project on the table. The upper in the link below is what you are getting minus the bolt assembly and charging handle. I prefer PayPal, but any form of US funds will work. If the link does not work, please email me and I will send you photos!
