SB Tactical HBPDW 5.56/.300 BLK 3-Position AR Pistol Brace - Black
The SB Tactical HBPDW Pistol Stabilizing Brace brings the compact profile of the Q Honey Badger-style PDW brace to compatible AR-15 lower receivers. Designed for 5.56 NATO and .300 Blackout AR pistols, the HBPDW combines a proprietary buffer system with three-position adjustability to create a complete, low-profile rear assembly.
The HBPDW measures approximately 5.75 inches when collapsed and 10.25 inches when fully extended. Its integral ambidextrous QD sling socket supports right- or left-side sling attachment, while the included proprietary buffer, spring, buffer tube and mounting components provide the parts required to replace a conventional carbine receiver extension assembly.

Compatibility Notes
This HBAR-01-SB model is intended for compatible 5.56 NATO and .300 Blackout AR configurations using a Mil-Spec bolt carrier group. It should not be confused with the separately configured HBAR9-01-SB 9mm HBPDW. The HBPDW uses proprietary buffer-system components and is not designed to be combined with a standard carbine buffer, spring or receiver extension.
Confirm lower-receiver and bolt-carrier compatibility before installation. SB Tactical recommends installation by a certified armorer or qualified gunsmith. The owner is responsible for ensuring the completed firearm complies with all applicable federal, state and local requirements.
