Does the ATF's New Rule on Stabilizing Braces Spell the End of Micro Conversion Kits?
This video by William Kirk of Washington Gun Law explains how the ATF's new rule on stabilizing braces (Rule 2021R-08) is expected to effectively end the use of Micro Conversion Kits (MCKs). The ATF is reclassifying firearms with attached braces as Short-Barreled Rifles (SBRs) if they do not meet specific weight and length criteria. Owners of affected firearms will face options of destruction, forfeiture, or registration with a tax stamp.
