The Magpul BTR arm brace is a stabilizing accessory engineered to transform the way you handle large-format pistols with a single hand. Designed for AR pistols equipped with Mil-Spec carbine receiver extensions, the BTR combines Magpul's proven design philosophy with practical features that make one-handed shooting more controllable and comfortable. Whether you're at the range, in training, or deploying your pistol in a defensive role, this black tactical brace offers a straightforward solution to improving stability and control without unnecessary complexity.
What sets the BTR apart is its thoughtful balance of function and simplicity. The brace uses high-strength polymer and metal construction to deliver durability without bulk, and the toolless length-of-pull adjustment lets you dial in your fit on the fly—no gunsmith visit required. The integrated QD cup is ambidextrous, so whether you're left or right-handed, you can mount a sling and apply tension while firing to anchor the gun against recoil and drift. An M-LOK compatible slot adds another sling attachment point if you want mounting flexibility.
This is purpose-built equipment for shooters who want genuine improvement in one-handed employment without gimmicks. Magpul engineered the BTR to work specifically with Mil-Spec carbine receiver extensions—check your upper and lower to confirm compatibility before ordering. As always, final firearm configuration is subject to federal, state, and local law; the user is responsible for understanding and following all applicable regulations.
