How do I get a determination if my “brace” device makes a pistol a short-barreled rifle (SBR)?

In addition to ATF’s list of commercially available firearms sold with “stabilizing braces” and common weapon platforms equipped with “stabilizing braces” that qualify as SBR, any other firearms equipped with a “stabilizing brace” or rearward attachment may be submitted to ATF’s Firearms and Ammunition Technology Division for classification.

Firearms may be submitted to:

Chief, FTISB
244 Needy Rd.
Suite 1600
Martinsburg, WV 25405

A prepaid return shipping label should be provided when submitting to prevent delay of the return of the sample.
