Grab a frame blank to start your 80% GLOCK build.

To assemble your GLOCK® kit, you need one of these 80% GLOCK® frames. These firearm blanks are compatible with newer GLOCK® components, including factory and aftermarket GLOCK parts.

What is an 80% GLOCK® Frame?

These frames are non-functional, and unfinished. They’re considered firearm frame blanks, which means they cannot accept the components necessary to make them into working firearms. You, the builder, must finish fabricating the frame. Once fabrication is complete, your frame is considered a firearm under federal law, and it can accept parts like a barrel, slide, trigger, and the pins and springs needed to function.

Assemble your completed frame with a GLOCK kit.

Our available GLOCK build kits include all the parts needed to assemble your finished frame. Magazines are sold separately.

80% GLOCK Frame Compatibility

These frames are compatible with certain factory GLOCK® handgun models. Choose the frame option below, based on the model and caliber you wish to fabricate and assemble.

Federal vs. State Law

Some states have banned 80% frames 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).
