Weights (INCLUDING Barrel Nut) in Ounces:


Under controlled laboratory tests the handguards can support a force of 90 pounds in any direction, and 600 pounds along their length – more than even extreme users require. We field test every handguard configuration, firing thousands of rounds in tortuous conditions. Once finished, we bring them back to the lab and inspect the handguards for flaws or cracks. The resulting high-strength design is unique enough that it’s covered by a US patent! We can even hang 40 pound dumbbells from the end of all handguard models with no signs of bending.

Thread Count:

Both our .223 and .308 barrel nuts use the standard Yankee Hill thread count.


ID = 1.75″

OD = 2.00″

Lengths: Measured from tip of end cap to end of jam nut (i.e. fully installed length).

Barrel Nut Torque:

As with any standard aluminum barrel nut, the recommended torque is 35-40 ft-lb.  A small spot of Moly Lube is also recommended but not required.

Carbon Fiber:

BA’s signature handguard is built on a platform of materials proven through aerospace applications and innovative mechanical design. It is composed of several composite yarns in a lattice that minimizes weight and maximizes stiffness and strength. Every yarn within the tube is formed from T700 carbon for strength and stiffness and shrouded within a protective jacket for all-weather durability and abrasion resistance. This jacket prevents cracking (common in filament wound handguards) and splinters (common in roll-wrapped handguards).

Heat Rejection (Barrel Cooling):

Brigand’s open-architecture braid encourages natural air-flow, allowing heat to be blown off quickly, and provides excellent exposure for radiated heat to escape. Under sustained fire the barrel will be cooler and the handguard will cool up to 50% faster after firing than with any enclosed guard. This improves barrel life and decreases heat signature duration.

Frequently Asked Questions

Return Policy?

We will cover your return shipping cost! Our goal is to provide you with technology that you are 110% pleased with. If you receive your handguard and wish to return it for any reason, just let us know within 60 days and we will take care of it. No questions asked.


Yes, the rails take well to cerakote! We recommend baking at a max of 250 degrees Fahrenheit.

Compatible with piston driven systems?

Generally, no. Specifically we have tried the Adams Arms piston design and found that it is not compatible with our barrel nut system.

Are Brigand Arms rail segments built for precise accessories?

Yes! Our pic rails efficiently maintain zero for precise accessories like laser aiming devices or range finders. They also support general accessories like grips and flashlights. The only use they are not good for is back up iron sites (BUIS). If you want to use BUIS, please use Atlas. It is developed specifically for BUIS.

Tightening the Jam Nut

You can use any standard spanner wrench to cinch down the jam nut, or you can use a strap wrench, OR simply give the jam nut a tap with a screwdriver. We’ve used this jam nut wrench ourselves, if you need to get one.

Compatible with .300 Blackout rifles?

Yes! You should order the “AR-15” barrel nut option when you get your handguard. You will have to remove your current barrel nut and install the Brigand barrel nut, which is a standard free-float style barrel nut.

How does the Blade's shorter side differ in length from its longer side?

The listed lengths (i.e. 7″, 9″, 12″, 15″) found on the Specs page refer to the long side of the handguard. The shorter side is always 1.15” shorter than that for all blade handguards.
