Hello all looking for a little more clarification if possible, So i am a FFL 07/ SOT 2. As far as "manufacturing" i am looking to take a stripped lower say made by like Aero precision or Similar, and assemble and make my own firearm and then selling it completed. I know i need to fill out the forms for manufacturing it, but the part im a hair lost on is do i then need to Laser engrave all my info somewhere on the lower as well since i technically "Made a firearm", or do i just Fill out the form 2 and good to go. I just got off the phone with my atf agent and instead of giving me a straight answer just gave me a huge run around that got me nowhere. So any info is helpful. Thanks!
