Prior to and after the expiration of the 120-day tax forbearance, can I continue to possess my short-barreled rifle (SBR) equipped with a “stabilizing brace” if I have timely submitted my application to register my firearm?
Yes, but registrants should maintain proof of submission as evidence of continued lawful possession.
