Complete JP Enterprises 24" Supermatch AR-15 upper receiver. 24" heavy cryo-treated .223 Barrel with JP muzzle break. Adjustable gas block, Black fluted high rise receiver. Match bolt and gold TiN coated carrier. Looks unfired and most probably is. (I bought this from someone at a local gunshow a few years ago who said it was brand new, I've never fired it or mounted it) extremely rare and hard to find. No longer offered in this configuration. SPF (Price reduced looking for a good home) Pictures available on request.
Thanks for looking.
