What Are Pistol Braces? Complete Guide to Current Laws and Regulations (2025)

A pistol brace is a forearm-strapping device that provides shooting stability. As of 2025, pistol braces are legal at the federal level after the ATF's restrictive rule was vacated nationwide. A pistol brace (also called a stabilizing brace or arm brace) is a rear-mounted firearm accessory that attaches to your forearm using Velcro straps. Originally designed to help disabled veterans fire AR-style pistols one-handed, these devices sparked one of the most complex regulatory battles in firearms law history. On July 17, 2025, the legal uncertainty finally ended when President Trump's Department of Justice dismissed its appeal in Mock v. Bondi, officially ending federal restrictions. However, years of conflicting ATF rulings, court cases, and regulatory changes have left many gun owners confused about what's actually legal and what compliance steps may still be necessary at the state level. If you're looking to buy a pistol brace now that restrictions have lifted, it's more important than ever to stay informed. This guide cuts through the confusion with current facts, practical compliance advice, and clear explanations of your rights as a gun owner in 2025. Key Insights
