I would like to put a side-folder on a Draco. Would it be possible to do the following: 1. Have an out of state smith switch the rear trunion and add a side-folding mechanism. 2. Have him ship it to my LGS as a regular pistol. 3. Apply for and receive tax stamp. 4. Obtain the desired stock. 5. Manufacture an SBR myself by attaching a stock to the side-folding mechanism. I wouldn’t do this without a love letter from the BATFE, and I was wondering if anyone had already asked.
