Pin and weld suppressor?

I dont want to SBR anything. I travel across state lines often. At least a couple of times a month and I dont want to have to do a form 5320.20 everytime I do so. I want to be able to run a rifle stock because I like to use a rear bag for far away shots and pistol braces dont ride a bag for sh!t.

As for the $200 for the pin and weld, I do my own pinning and welding. 10 seconds of welding with a tig isn't going to cost me anything.

Just FYI, interstate travel is not that difficult. You file a form that is good for 12 months. Every January I file for the states I might travel to (matches, family, vacation, etc.).
