Description
The BDA Arm Brace installs onto AR-15 style pistols with Mil-Spec carbine and A5 buffer tubes, or cylindrical pistol receiver extensions to deliver a brace for one-armed firing. The large fin provides plenty of surface area for good contact with the forearm for one-handed use.
Magpul reliability in an optimized stabilizing accessory.
An integral QD socket at the rear of the brace supports a true ambidextrous sling attachment point and is perfectly located to provide sling tension for extra stability when the pistol is pushed forward. The BDA Arm Brace is not adjustable, fixes into one location, and includes interchangeable clamps to fit different receiver extensions. Made in the USA.
