Hello, I am looking at building my first SBR, I actually have everything together to build it now using a Sig Brace and KAK buffer tube, but I am debating selling those and processing the Form 1, and giving me more time to save for an optic and possibly the UBR stock. The Form 1 seems pretty self explanatory with the exception of section 13-Law Enforcement Certification. How does this exactly work?? I live in Tacoma, WA and what would I do, schedule a meeting with the City of Tacoma Chief of Police??
