Building your own handgun or AR-15 at home is a great alternative to just buying a retail gun (with unnecessary accessories or the wrong configuration) and paying extra at the gun store. Picking up one of these polymer 80% receivers is the way to do it. The ATF says it’s legal to build a gun at home from scratch, with no paperwork required (just check your local and state laws, too). The best part? These 80% frames and lowers are all compatible with their corresponding Glock® Gen 3 handgun parts or mil-spec AR-15 parts.

Glock® Compatibility

  • The PF940C kit is compatible with the Glock® Gen3 19, G23 (3-Pin), and the G32.
  • The PF940v2™ is compatible with the Glock® 17, G22, G24, G31, G34, and G35.
  • The PF940SC is compatible with the Glock® 26 and G27.

No Experienced Required to Build

The best part about building your own handgun with a frame blank is that it requires few tools and very little equipment to complete. Polymer is easy to cut and drill with basic tools, and the entire project should take less than 2 hours, even for first-timers! Once your frame blank is completed, simply assemble it with the appropriate factory Glock® parts or aftermarket kits, and you’re ready to hit the range.

Not a Firearm Under Federal Law

These un-finished 80% frames and 80% receivers are not considered firearms under federal law, nor does the ATF consider them firearms. Because they are not functional, they can be shipped like any other product to most states. They do not require an FFL, background check, transfer fee, or other special taxes or paperwork.

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.
