LOWER PARTS KITS (LPK) LOWER BUILD KITS BUFFER TUBE KITS & PARTS

RTB branded Lower Build Kits come with industry leading LPK components along with premium fire control group components. The price differences between our RTB kits and the other kits is largely due to the premium parts used in our kits. There's a night and day difference in look, feel and durability between our triggers and the other NON-RTB kits.
