Bomb proof setup. The sr5.56 piston upper is all roll pinned together and is super smooth. Has an aero breach charging handle and the lower has a larue flat face trigger. Has a vortex viper pst 1-4 in an adm qd mount and a crimson trace light with pressure pad. Also have a trijicon rmr on a 45 degree mount I can add in. It’s battle ready. Text me at 9037245344. Cash is preferable or I’ll trade for a motorcycle hopefully a sport bike. Doesn’t have to be running but I do want something worth what my setup is.
