engineer39This is a BRN-4 barrel that was reprofiled by Nefarious arms to match their SOCOM profile, and cut for the new A4/5 upper receivers. The upper was pinned at one point, but it was done cleanly and could be re-pinned or used as is. Comes with an NA5 gas block, random flash hider, and blemished HAUS barrel nut.
Price is shipped and insured.
