I have a 8in Ballistic Advantage Modern series barrel with pinned gas block and a BCM 7in KMR rail. While this upper is enjoyable to shoot, I find myself not using it that often, and I want to consolidate my AR's to 5.56. I would like to trade for a 10.5 or 10.3 barrel or 9"ish rails. I would be willing to trade complete uppers or for various combinations of parts. Shoot me some offers
