Brigand BLADE, AR-15 Carbon Fiber Quadrail Handguard

Brigand BLADE, AR-15 Carbon Fiber Quadrail Handguard

Barrel Nut:

We make our own barrel nut and jamb nut from 7075 Aluminum and Chromally steel . It weighs a total of 1.4 oz (far lighter than any other free float barrel nut + jam nut you will find). All weights listed INCLUDE the barrel nut weight (note that many of our lightweight competitors do not include the barrel nut weight in their weight calculations!)



Patented Carbon Fiber Open Structure

The BA handguard concept is built on a platform of materials proven through aerospace applications and innovative mechanical design. A large component of this is the braided carbon tube; technically called ‘Open-Architecture Composite Structure’ or O-ACS for short. The O-ACS geometry is designed in the computer using proprietary software. It is braided from special 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, 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). Solid metal end-caps provide rock-solid mounting on the receiver, and protection from impact on the fore end.



Strength

We can hang 40 pound dumbbells from the end of it and swing them around with no signs of bending. Under controlled laboratory tests the handguards can support a force of 100 pounds in any direction, and 400 pounds along their length – more than even extreme users require. We field test every handguard configuration, firing thousands of rounds in tortuous conditions, then bring them back to the lab and inspect there are no flaws nor slowly developing cracks. Dozens of iterations have led to the current braid that we use. The resulting high-strength design is unique enough that it’s covered by a US patent!



Heat Rejection

Not only does the Brigand handguard withstand the heat of sustained firing, it also rejects barrel heat faster than most handguards. Heat leaves a rifle barrel through convection (air-flow past the barrel) and radiation (infrared ‘glow’). Does this exposure mean your hand will get hot? The open-architecture guard will warm up to operating temperature faster: However, under sustained fire the barrel will be cooler and the handguard will cool faster after firing than with any enclosed guard. This improves barrel life and decreases heat signature duration.
