Here is a response and some guidance from SB Tactical:
"We understand your concern – and nothing has changed, yet. We got wind a few days ago that the ATF was finally publishing guidance on braces which we have been requesting for years. Instead we got the attached PROPOSED DOJ draft document that will be going live on the federal registry tomorrow and will be open for comment for only 2 weeks. The ‘guidance’ doesn’t clarify anything – see page 7.
What weight and length?
What length of pull?
This article helps explain things as well: https://www.thetruthaboutguns.com/no-pistol-braces-are-not-banned-but-atf-is-attempting-further-restrictions/
Here are some suggested bullet points if you decide to comment:
• This document is not guidance to industry but a power grab by the ATF.
• No manufacturer or consumer can look at this document and know what ATF thinks is illegal or legal.
• It does nothing to limit the ATF but instead expands its authority by saying it will rely on manufacturer “intent” and multiple “factors” that have no specifics
*• Its “holistic” approach is designed to ensure that ATF has unlimited discretion to make unprincipled ad hoc determinations *
• This invites future ATF moves to register and ultimately confiscate accessories
• No arm brace or firearm sold with a stabilizing brace is safe under this approach
*Please share this and comment if you are able to do so – this issue goes far beyond just pistol braces and could affect every gun owner in the country if we leave the ATF unchecked. *
