This kit does not contain a firearm, frame, receiver, or signaling device. None of the components included in this hardware kit can be assembled into a firearm or signaling device without additional (3D printed) parts that you must supply. However, by purchasing this kit, it is understood that you intend to use it to manufacture a firearm or signaling device. Seller is not the manufacturer of the resulting firearm or signaling device; you (and/or your designated FFL) assume that role.

Due to the ever-evolving laws regarding home-built, 3D-printed firearms and signaling devices, commonly referred to as “ghost guns,” we cannot guarantee the legality of completing or possessing this kit in your jurisdiction.

By purchasing this kit, you acknowledge your intent and ability to comply with all applicable local, state, and federal laws. You also accept full responsibility for the legality and safety of the firearm or signaling device once assembled, as well as for the assembly process itself.

Always prioritize safety by wearing appropriate protective gear (eye and ear protection, gloves, face shields, long sleeves) when building and operating firearms or signaling devices, particularly those with 3D printed components. If you lack confidence or skills, consider seeking assistance from a qualified gunsmith (FFL).  Any resulting firearm or signaling device should additionally be reviewed by a qualified gunsmith (FFL) before testing to ensure safety.
