AR15 Pistol Kit

AR15 Pistol Kit

Available in 5.56/.223 and 300 Blackout.

The AR15 pistol became wildly popular in recent, offering shooters the opportunity to enjoy a shorter, lighter weapon system that still boasts comfort, control, and accuracy. To offer you the same opportunity to build a custom AR pistol -- of course by using a quality 80% lower -- we partnered with top OEM AR parts manufacturers to bring you the best barrels, forged uppers, free-float handguards, and M16 BCGs, all at great prices.

Why Our AR-15 Pistol Kits?

Unlike other build kits that include a stripped lower receiver, our kits feature an 80% lower. Because the 80% lower isn't considered a firearm by the ATF or federal law, your kit ships directly to your front door and you don't get stuck paying a premium that other gun shops have to pass onto their customers. There are no extra taxes or special fees, no FFL transfer, and no paperwork to deal with. All you need to turn your box of parts into a range-ready pistol is an AR-15 jig (which includes the required bits to cut and drill your receiver).

In addition to this convenience, we provide utter quality:

  • All barrels are forged from MIL-B-11595 E steel (4150 or Chromoly Vanadium)
  • All stainless barrels forged from Crucible 416R steel, offering sub-MOA accuracy
  • All BCGs are M16 in profile with chrome lining and properly staked gas keys
  • All stripped upper receivers forged from mil-spec 7075 T6 aluminum
  • All buffer assemblies and lower parts kits are mil-spec in fit and finish
  • All barreled uppers are test-fired to ensure proper assembly

Your 80% lower is mil-spec in fit and finish, too.

The included lower receiver blank you'll receive features mil-spec threads and fittings, ensuring an easy install with the provided parts kit and buffer assembly. Your receiver ships with a mil-spec hardcoat anodized finish, ensuring it matches perfectly with your barreled upper and all other accessories and components you install.

300 Blackout Pistols: Configured for Performance

All 300 Blackout kits feature the appropriate pistol-length gas system to ensure your new pistol reliably cycles supersonic and subsonic loads, suppressed or un-suppressed. Each 300 BLK kit is also outfitted with a 1:7- or 1:8-twist barrel to ensure both light and heavy loads are appropriately stabilized for MOA accuracy.

State Laws May Vary

Contrary to federal law, some states have either restricted or banned the sale, transfer, and ownership of 80% lowers, firearm blanks, and other gun parts. Because of these restrictions, we cannot ship our products to certain states. Please confirm whether your state is restricted on our Shipping & Return Policy before placing an order. We cannot fulfill orders to restricted states if placed.
