ATF to Gun Makers: You’ve Got 7 Days to Mark Your Parts

Gunmakers have been after the ATF about the regs re: marking the bits which (for some reason) constitute a “complete” firearm (e.g. finished AR frames and receivers). Whose job is it anyway (given that full guns are often assembled from the parts later) and when do they have to do it? Needless to say the bureaucrats who handed some 2000 firearms to Mexican drug thugs went for the strictest possible interpretation of the law. And called themselves “reasonable” for doing so. As follows . . .

Under the regulations, section 478.92, firearms required to be marked at the time of manufacture include both “complete weapons,” and complete frames or receivers of such weapons that are to be sold, shipped, or otherwise disposed of separately. Because identifying firearms is an integral part of the manufacturing process, and sections 923(i) and 478.92 do not specify a time period in which to identify firearms, licensed manufacturers are required to mark them during the manufacturing process. Reading the marking requirement for complete weapons in section 478.92(a) together with the seven day recordkeeping requirement for complete firearms in section 478.123(a), ATF concludes that it is reasonable for a manufacturer to have seven (7) days following the date of completion (to include a firearm in knockdown condition, i.e., complete as to all component parts, or a frame or receiver to be sold, shipped, or disposed of separately) in which to mark the firearm and record its identifying information in the manufacturer’s permanent records.

    What does this mean?

      I was curious about this as well.

      IMO it is just another way for the gun grabbers to increase the cost to manufacturers (i.e. Economics 101 – all costs are ultimately passed on to the end user) and therefore make our hobby more expensive. From the GG’s playbook, if we can’t outlaw guns, let’s make it harder to buy or use them.

        That’s a thoroughly unhelpful tinfoil hat answer.

        What does it mean to mark the parts? What is the stated purpose of doing so? Is it serialization for FFL purposes? Isn’t that done during manufacturing?

      My guess is it means they have to stamp all of the parts. But what about contract manufacturers that do not caste the actual part? Read the ruling and post questions . . . drink lots of coffee . . . 🙂

    How about we mark criminals within seven days of conviction? Tattoo Loser right across the forehead.

      please add to your list the bureaucrats at ATF who came out with their version of “reasonable”
