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 stabilising 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.
Improved stability in a slim profile for large-format pistols.
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. Made in the USA.
