Magpul BDA Fixed AR Pistol Stabilizing Brace for Mil-Spec, A5 and Pistol Buffer Tubes - Black
The Magpul BDA is a fixed-position AR pistol stabilizing brace designed to support one-handed firing across a broad range of receiver extensions. Its large fin provides forearm contact, while interchangeable clamps allow installation on Mil-Spec carbine, A5, and many cylindrical pistol receiver extensions.
A rear QD socket provides an ambidextrous sling attachment point that can also be used to apply stabilizing sling tension. Durable Magpul polymer and corrosion-resistant metal fasteners support dependable use without an adjustable stock-style mechanism.
