GLOCK® Compatible 80% Frame

GLOCK® Compatible 80% Frame

It's no secret GLOCK® reigns supreme as one of the world's most popular pistol platforms. Between a plethora of calibers, endorsement by militaries and law enforcement across the globe, and endless configurations for sport, defense, carry, and plinking, there's a GLOCK® handgun for everybody. But what if you could build a truly custom GLOCK®-compatible handgun with the same, exact specifications, dimensions, features, and performance for less? That's exactly what you'll get with one of these GLOCK®-compatible 80% frame kits. 

80% Frame, Jig & Tooling Included

Each 80% frame kit conveniently includes the required drill bits and components for drilling your frame blank and making it ready for final assembly. The provided jig is perfect for veterans and first-time builders, showing you where to cut and drill the frame without any measurements or special calculations required.

All you need is a few hand tools:

  • Handheld drill
  • Bench-top vise
  • Dremel, snips, or files
  • *Drill press (optional)

*The frame can be easily cut and finished with snips, and flat and round hand files, though each kit includes an HSS end mill. Unlike aluminum 80% lowers, you can safely cut the polymer 80% frame by gently milling with a drill press and the end mill.

Not Firearms Under Federal Law

Unlike finished GLOCK® frames, the ATF and federal law do not recognize GLOCK®-compatible 80% frames as firearms. These units are considered firearm blanks, non-functioning gun parts that are not regulated as guns. That means you don't need to order your frame through an FFL, pay any dealer or transfer fees, or conduct a background check. Some states have banned 80% lowers and certain firearm parts, 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).
