The Rifle or Pistol Lower Build Kits that start with RTB utilize our true Mil-Spec components that are sourced from well established .mil contractors. Right To Bear 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 due to the premium parts used. There's a night and day difference in look, feel and durability between our triggers and the other NON-RTB kits, such as Palmetto State Armory kits. The Lower Build Kits that are not labeled "RTB" are still good kits and are comparable in quality to other major brands, such as PSA and Anderson Manufacturing.
Why are Right To Bear kits better than the majority?
The Fire Control Group components in our RTB branded kits are manufactured to the exact standards as government parts other than the dimensional differences to prevent auto or burst fire. They are Mil spec in processing and the materials used are based off the current Mil standards.
