Description
The Magpul BSL Arm Brace is a stabilizing arm brace purpose-built to improve single-handed control of large-format AR pistols. Engineered around a Mil-Spec buffer tube (tube not included), the BSL delivers a secure, adjustable platform for AR-pistol shooters looking to add shoulder stability without converting to a full rifle stock.
Constructed from durable black polymer, the BSL keeps weight to a minimum while standing up to hard use in the field or at the range. Its low-profile design follows Magpul’s well-known styling cues, integrating cleanly with any AR-pistol build, and the brace is ambidextrous out of the box for right- and left-handed shooters alike.
Up front, the BSL features M-LOK compatible slots for attaching a hand stop, sling mount, or other M-LOK hardware, while the rear incorporates an integrated ambidextrous QD cup that accepts any standard quick-detach sling swivel for fast, versatile sling attachment on either side. The result is a clean, lightweight stabilizing brace that drops onto a Mil-Spec carbine buffer tube with no modifications required. Designed and manufactured by Magpul Industries in the USA, the BSL Arm Brace is sold here as the brace only – the buffer tube is not included.
