AR Rifle Kits

AR Rifle Kits

Quality, mil-spec, affordable AR-15 and LR-308 rifle kits. But why ours, specifically? For starters, parts kits aren't legally considered firearms. Even if you purchase a billet or forged 80% lower, these parts kits do not yet function. Not until you fabricate your receiver blank with the right 80% jig and tooling. That means your parts kit ships direct to your door, minus all the extra taxes, fees, and FFL paperwork. But cost savings aren't the only reason to consider our 5.56/.223 and .308 build kits:

Industry-Leading Specs for Each Rifle Kit

  • 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

What's Included With Your AR Rifle Kit

Each rifle kit is considered complete from muzzle to buttstock. Aside from cutting and drilling a separately purchased lower receiver blank, everything you need to assemble a functional rifle ready for the range is included:

  • (1) AR-15 or LR-308 Upper Assembly
  • (1) Mil-spec Lower Parts Kit
  • (1) Buffer & Buttstock
  • (1) Bolt carrier group

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.
