SB Tactical HB AR Brace Black for 5.56/.300 Blackout Rifles

The SB Tactical HB AR Brace for 5.56/.300 Blackout rifles is a lightweight, short-profile stabilizing brace designed to give you a more stable platform when running a pistol-configured AR lower receiver. Built by Q and adapted from their proven Honey Badger design, the HB brace adds a second point of contact for improved control and handling without the weight or bulk of a full stock. Whether you're working with 5.56 NATO or .300 Blackout, this brace delivers the maneuverability of a pistol platform with the stability you need for accurate shooting. It's US veteran designed and manufactured in the USA.

The brace features a 3-position adjustable design, so you can dial in the length that works best for your setup and shooting style. The integral, ambidextrous QD sling socket lets you attach slings without extra hardware, and the included adjustable nylon strap ensures a secure, comfortable fit. At just 12 ounces (16 ounces with buffer and spring assembly), it keeps your rifle lightweight and handy—ideal if you're building a compact AR for close-quarters work, truck gun duty, or specialized applications. The low-profile, short footprint makes it easy to handle in tight spaces and from vehicles.

Compatible with standard mil-spec bolt carrier groups and AR-15 lower receivers, the HB brace integrates seamlessly into existing builds. The complete assembly arrives with everything you need to install it right out of the box: buffer tube, buffer and spring assembly, castle nut, castle nut wrench, and adjustable strap. No guessing, no hunting for parts. SB Tactical products are designed and intended only for use as forearm braces to provide a more stable firearm platform; they are neither designed nor intended to be fired from the shoulder.

Frequently Asked Questions

Is the SB Tactical HB AR Brace compatible with my AR-15 lower?

Yes, as long as your lower receiver is mil-spec and uses a standard mil-spec bolt carrier group. The brace attaches to the buffer tube area just like a traditional stock would.

What's included with this brace, and do I need to buy anything else to install it?

The complete assembly comes with the brace itself, buffer tube, buffer and spring assembly, castle nut, castle nut wrench, and adjustable nylon strap. You have everything needed for installation out of the box.

Can I adjust the length of the HB brace?

Yes. The brace features a 3-position adjustable design, allowing you to set it at 5.75 inches (collapsed) or 10.25 inches (extended), plus an intermediate position, so you can find the length that works best for your build and shooting preference.

How much does this brace weigh, and will it balance my rifle?

The brace weighs 12 ounces on its own (16 ounces with the included buffer and spring assembly), keeping your AR pistol platform lightweight and maneuverable—an important advantage over heavier traditional stocks.
