Build a custom pistol with an 80% frame.

We've got the most popular 80% frame options available today. Makers like Polymer80 and Geisler Defence produce high-quality frame blanks that fit factory parts, are made of tough polymer and aluminum construction, have improved grip ergonomics, and provide optional Picatinny rails for lights and lasers.

What is an 80 Frame?

An "80 frame" typically refers to an 80% firearm frame, which is an incomplete frame that requires additional machining and assembly to become a functional firearm. The term "80%" refers to the level of completion, indicating that the frame is roughly 80% finished and lacks certain features, such as trigger group holes, selector switch holes, or other necessary machining operations.

These 80% frames are generally made from materials like polymer or metal alloys and are designed to be partially finished, lacking certain features or machining that would make them considered complete firearms.

The specific process of completing an 80% frame can vary depending on the firearm platform and the manufacturer. It typically involves using specialized tools and techniques to machine or drill out the remaining material, add necessary holes or cavities, and perform other required modifications. Once the machining process is complete, the user can then assemble the necessary components to create a functional firearm.

80% Frames: Serialization & State Restrictions

Some states require serialization of your 80% handgun frame before fabrication. Other states have banned 80% frames, certain firearm parts, and other products we sell. Check your local and state laws, and please confirm whether we can ship to your state before ordering.
