Our AR and handgun (1911, Sig P320 and GLOCK-compatible) Pistol Kits represent the easiest, most affordable way to build and own your very own, top-tier pistol for pennies on the dollar. With configurations available for true pistols and SBRs alike, our 100%-made-in-the-USA kits feature mil-spec Chromoly or Stainless Steel barrels for MOA accuracy.
Each of our AR Pistol Kits includes a fully-built upper with gas system, threaded muzzle, and receiver, as well as a free-floating M-Lok, Keymod, or Picatinny handguard. All uppers feature M4 flat tops and M4 feed ramps, while each lower features a mil-spec parts kit with buffer, tube, and stabilizing brace. All Pistol Kit 80% lowers are built from mil-spec 6061 T6 billet or 7075 T6 forged aluminum, and each kit comes finished with a mil-spec type III Hardcoat Anodized finish.
Kits Work with "Retail" Gun Parts
All handgun pistol kits are guaranteed to be 100% compatible with their retail counterparts, including all factory and aftermarket components. Our 1911 kits feature a lightweight 80% frame machined from 6061-T6 billet aluminum, shaving off 60% of the original 1911's weight! The Sig P320 kits feature factory components to provide that legendary quality, and all GLOCK-compatible kits interface with any Gen 3 GLOCK components you'll find on the market.
