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.
