Here is a deal. I am selling my brand new RRA CAR upper reciever. This unit is complete with RRA lapped bolt carrier, bolt, and charging handle. Never been fired or installed on a lower. This is a flat top upper WITH M4 FEED RAMPS, 16" CAR barrel with mid length handguards and A2 flash suppressor. Has weaver rail gas block. Now for the extras, all of which are included in the $300 price: Yankee Hills (BMAS) fold down front site ($79 value) installed on gas block. Four aperture BUIS style fold-down rear site ($89 value). Plus, if you are buying the upper in anticipation of the ban ending, I will also supply a RRA post-ban muzzle break to be PERMANENTLY INSTALLED later in the event the ban doesn't go away. PLEASE NOTE: IT IS CURRENTLY ILLEGAL TO INSTALL A "PRE-BAN" CONFIGURED UPPER ON A "POST-BAN" LOWER. JUST DON'T DO IT! All of this for $300 SHIPPED to your location.
