The Magpul BDA Arm Brace (brand part no. MAG1251-BLK) is a straightforward, Magpul-engineered solution for improving single-handed control of an AR pistol. It fits Mil-Spec carbine and A5 receiver extensions as well as dedicated pistol receiver extensions, so it works across a wide range of existing builds without a special tube. An integrated rear QD cup gives ambidextrous sling mounting options, and the brace’s large lateral surface area provides plenty of forearm contact, letting you apply sling tension for real stability instead of just resting your arm against the buffer tube.
