Swiss Arm 553P SBR build advice needed

General Firearms NFA

Hello everyone,

Lately I have a growing interest in the 553P and want to make a SBR on it. I have done some research but couldn’t find much information or advice on this specific project.

I have never done a SBR project before by myself, so this project will be a challenge for me. I am looking for everyone’s insights, experience or advice. I greatly appreciate that.

There are numerous posts detailing the 553, including info on filing a form 1 to add a stock. A quick search will help you but what about the process specifically do you need help with? ATF forms, actual stock install, 922r compliance?
