I have a RRA Flattop complete Minus b/bc/ch. The barrel is a Bushmaster 1/9 16" hbar with a LE Compensator on it. I bought this from RBPrecision a month ago. It has seen about 1200 rounds from what they quoted, I have never shot it. I would rate the upper 99% there is one nick on the left hand side. It has been fitted on a RRA lower.
I am asking $310 shipped complete. I can throw in a DPMS rear maginol sight for an extra 50 bucks.
