The Magpul BSL Arm Brace for AR15 with Milspec Carbine Receiver Extensions, Black is a pistol brace that fits AR15 with Milspec Carbine Receiver Extensions.
The BSL Arm Brace installs onto AR-15 style pistols with Mil-Spec carbine or VLTOR A5 buffer tubes to deliver an adjustable, fin-style stabilizing brace for one-armed firing. The extended fin provides contact with the forearm of the trigger hand, and the adjustment latch supports one-handed adjustments for a custom fit. 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. Two M-LOK slots provide additional options for sling mounting.
Designed and intended for use as a stabilizing accessory for one-handed firing
