Our 80% AR 15 Builds are designed and packaged for you to get almost everything you need to build your own custom AR-15 from the ground up! These builds are also one of the most cost-effective and budget-friendly ways to either start your arsenal or add to it.
Some states have banned 80% lowers and certain firearm parts or rifle builds, or have otherwise restricted the sale and ownership of products we sell. So, be sure to check your local and state laws. We can’t ship our products to certain states. Please check our Shipping & Return Policy before placing an order (see restrictions).

Why Build, Not Buy?

An AR 15 build  is the easiest and most cost-effective route for you to build a custom AR-15. Like everything in our store, all of the components of our AR 15 Builds are made by hard-working Americans - right here on US soil. Why drive to big box store or buy a completed AR-15 (and pay a premium) when you can build it yourself? We make it easy, too. If you're new to the game, check out the intro guide below. If you already bought your rifle build, all you need to do is install the lower parts kit once you buy and complete your 80% lower ( sold separately). Then hit the range!

Each AR 15 Build Includes:

  • (1) AR-15 Barreled Upper Assembly
  • (1) Mil-Spec Lower Parts Kit
  • (1) Buffer & Buttstock
  • (1) Bolt carrier group w/ charging handle

Quality, Mil-Spec Rifle Parts

Our AR15 builds aren't just convenient, they're equal to or greater in quality than the typical "retail rifle". We partner with some of the nation's top gunsmiths and manufacturers to carefully piece together each build, ensuring MOA accuracy and utter reliability.

  • 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
