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.
