Is there an overall question you have about firearm definitions? Is there something we didn’t properly explain in the previous threads? I encourage you to visit the ATF’s website. They explain each firearm’s definition, provide examples, and give references to the corresponding federal laws and regulations. Just Google “ATF definition [firearm type]”.
