MAGPUL BTR ARM BRACE MIL-SPEC BLK

Description

The Magpul BTR is an arm brace built for the AR-pistol platform, designed to give shooters better one-handed control of a large-format pistol without adding bulk or complexity. It fits mil-spec carbine receiver extensions and uses a straightforward adjustment mechanism that lets you dial in length of pull quickly and without tools — a practical advantage when you need a repeatable setup across different shooting positions or users.

Sling integration is central to how the BTR improves single-handed handling. A single M-LOK compatible slot and an ambidextrous rear QD cup let you mount a sling in a position where tension actually works in your favor, pulling the pistol into your forearm and reducing muzzle wander during firing. That sling-tension geometry is the functional core of the design, not just a convenience feature for carry.

Construction is black polymer, consistent with Magpul’s approach to weight management without sacrificing durability. The brace is made in the USA and carries the same design language as the rest of the Magpul stock and brace lineup, so it integrates visually and ergonomically with other Magpul furniture on the same build. The tube is not included, so if you are starting from scratch you will need a mil-spec carbine receiver extension separately. For shooters building or upgrading an AR pistol who want a clean, no-frills brace with proven sling-mounting options, the BTR covers the essentials without unnecessary complexity.
