Frequently Asked Questions
What tools are required to complete this 80% frame?
You will need a hand drill or drill press, a Dremel tool or milling machine with router bits, and basic hand tools. The included jig guides the drilling and milling operations. Safety equipment like eye protection is essential.
Does this require an FFL transfer?
No. Because this is an unfinished 80% receiver, it is not classified as a firearm and ships directly to you without an FFL transfer, in compliance with federal law. Always verify your local and state regulations before purchasing.
What parts kit do I need to finish the build?
You will need a Glock® 19/23 Gen 3 parts kit (often called a Lower Parts Kit or LPK) and a complete slide assembly (slide, barrel, recoil spring) to finish the firearm. These are sold separately.
