The Magpul BTR Arm Brace for AR15 with Milspec Carbine Receiver Extensions, Black is a pistol brace that fits AR15 with Milspec Carbine Receiver Extensions.
The BTR Arm Brace installs onto AR-15 style pistols with Mil-Spec carbine or VLTOR A5 buffer tubes to deliver an adjustable brace for one-armed firing. The A-frame shape preserves Magpul aesthetics, and the adjustment latch allows for easy one-handed adjustment. The integral QD socket located 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. An M-LOK slot provides additional options for sling mounting.
