This kit gets you an upper assembly made from a 20" nitride-coated barrel and a 15" M-Lok handguard. You also get a buffer tube assembly and butt stock kit, lower parts kit. All you need are a lower, backup sights or an optic of your choice, mags, and ammo. Please note, this build kit  is configured for the LR-308.
