Description

That’s right, we have 5.56mm pistol build kits too.  This one’s barrel is more than adequate at performing to your short-range expectations but its 8.5″ length makes it super maneuverable.

This kit gets you an upper assembly made from a 8.5″ nitride-coated barrel and a 7″ M-Lok handguard.  You also get a buffer tube assembly with an SB Tactical pistol brace.  For the lower parts kit, you get one whose grip has been upgraded to a Magpul MOE grip. Finally, you get your choice of either forged or billet 80% lower receivers.  All you need are backup sights or an optic of your choice, mags, and ammo.
