Magpul Arm Brace Mil Spec Black MPMAG1079BLK

The Magpul BTR is a purpose-built AR arm brace engineered to enhance the single-handed control and stability of large-format pistols. Designed with Magpul’s proven approach to durability and function, the BTR delivers a clean, effective solution for shooters who want improved handling without unnecessary complexity. Its streamlined profile and classic Magpul aesthetics integrate seamlessly with modern AR pistols, maintaining a professional appearance while adding meaningful performance benefits.

Compatible with Mil-Spec carbine receiver extensions, the BTR installs easily and locks up securely. Its simplified adjustment system allows for toolless, single-handed length adjustment, making it fast and intuitive to set up in the field or at the range. The adjustment mechanism is built for durability and repeatability, ensuring the brace maintains its position during use while remaining easy to operate when changes are needed.

A key advantage of the BTR is its integrated sling support. An ambidextrous rear QD cup allows users to attach a sling in a variety of configurations, while the M-LOK compatible slot provides additional mounting flexibility. These features enable stabilizing sling tension to be applied during one-handed firing, significantly improving control, balance, and overall shooting stability. This setup allows shooters to maintain better muzzle control and reduce fatigue during extended use.

Constructed from high-strength polymer with reinforced metal components, the BTR is built to withstand hard use without adding unnecessary weight. The materials are chosen to deliver long-term durability while keeping the brace lightweight and comfortable. Every contour and feature reflects Magpul’s focus on real-world usability, from the smooth edges that won’t snag gear to the solid feel that inspires confidence during operation.

Designed and intended strictly as a stabilizing accessory for one-handed firing, the Magpul BTR represents a thoughtful balance of innovation and practicality. It’s an ideal upgrade for shooters looking to enhance control, improve ergonomics, and maintain a clean, reliable AR pistol setup. Proudly made in the USA, the BTR stands as another example of Magpul’s commitment to quality, function, and dependable performance.
