American Tactical Imports provides the tinkerer in you with everything you need to turn a stripped AR-15 lower into a working rifle. The barrel - the heart of any build - is a 16" M4 profile with 5.56 NATO chamber and Mil-Spec 1:7 twist. The 1/2x28 threaded muzzle features and A2 flash hider. The upper receiver and gas block are railed so you can add iron sights or a scope at your preference. The Collapsible M4 stock features 6 positions of adjustability for a proper fit to any sized marksman. The trigger guard is left out of the included lower parts kit in case you want to select your own or the lower you are using already includes one.

Just add a lower and sights and enjoy!

NOTE: The manufacturer mistakenly stamped the barrels on this kit ".223 Remington". The chamber is actually 5.56 NATO and rifles completed with this kit can shoot both .223 Remington and 5.56 NATO ammunition.
