80 Percent Lower

80 Percent Lower

Every 80 percent lower we sell is proudly made in the U.S.A. from quality billet aluminum (6061-T6), mil-spec forged aluminum (7075-T6), or weapons-grade polymer.

What is an 80% Lower Receiver?

Officially called a “receiver blank” by the Bureau of Alcohol, Tobacco, and firearms (ATF), an 80% lower is an unfinished receiver that isn’t considered a firearm. Cutting and drilling the lower at home with hand tools turns it into a ready-to-build firearm by legal definition. Whether it’s an AR-15 80 lower, AR-10 80 lower, 1911 frame, or a polymer 80% pistol frame, thousands of shooters have built reliable and accurate rifles and pistols with our units.

Do I need a license or FFL?

No. The Gun Control Act of 1968 says building a firearm for personal use without a license or paperwork is perfectly legal. The ATF also says 80% lowers are legal and aren’t considered firearms. So, you’re not subject to the same rules and restrictions when buying, shipping, owning, or building an 80 lower or other type of receiver blank.

  • No background check required
  • Ships directly to your front door
  • No transfer fees or FFL paperwork
  • No need to “register” an 80% lower
  • No serialization required by federal law
  • Compatible with retail gun parts when complete

These same rules apply to all receiver blanks, frame blanks, and build kits we sell at 80-Lower.com. State laws may vary so be sure to check your local and state laws, too. We can’t ship our products to certain states (see restrictions).

How Do I Complete an 80% lower?

Completing a lower requires no experience and usually takes less than two hours. All you’ll need to get the job done is an 80% lower jig. All available jigs include the necessary instructions, tools, and bits. There are four steps required:

  1. Cut the cavity for the lower parts kit
  2. Drill the hammer pin hole
  3. Drill the trigger pin hole
  4. Drill the safety lever hole

Instructional Guide: How to Complete an 80% Lower

Once you complete your lower, you can install a buffer assembly, lower parts kit, and pre-built upper receiver. Then you’re ready to hit the range! Completing an 80% frame for a Glock®-compatible handgun or 1911 is no different. Just drill the pin holes, cut the slide rails, and cut the barrel seat. The pistol jig instructions will tell you exactly what to do, and how. Order a complete build kit with an 80% lower included, and you can go from a box of parts to a functional AR rifle or pistol, 1911, or handgun in a single afternoon.

Your build awaits!
