Selling my complete JP Enterprises CTR-02 upper with 5.56 13.5" supermatch 1:7tw with JP adjustable block, low mass op system, and 3-port compensator. Comes with accessories shown (sling qd, pic rail, hand guard).
It is not pinned and welded. It currently has a crush washer. When I got this project started, I wasn't sure whether I would keep using the JP comp or use a DA brake for a suppressor.
