I gota build I did a couple years ago. Good rifle with alot of life left. Got to many and this one never gets shot anymore. Bcm stock and grip, aero/BA barrel, aero bcg and lpk. Aero scope mount with a vortex ranger 1-4( gen 1 viper pst) the barrel is 14.5 pinned and welded with a vg6 sl line muzzle brake. Mid length gas system. Mlok handguard. I will be keeping the light or could keep it on for extra $$. I'd like to get 850 shipped to your ffl.
