This video by The Late Boyscout features products found at SHOT Show 2017. The host goes around the largest and the most comprehensive firearms tradeshow and stops at the Brigand Arms to examine a 3.6 oz Carbon Fiber Handguard.
Brigand Arms features a line of ultralight forearms that represents cutting edge and modern weapons systems. The Carbon Fiber Handguard is a woven instrument that can support weight of up to 40 pounds. The unique “braid” design of the handguard is PATENTED technology that is intended for a shooter who needs uncompromising performance day in and day out.
The Carbon Fiber Handguard is built upon a platform of materials proven through aerospace applications and innovative mechanical design. The most prominent feature of the handguard is the braided carbon tube, which is technically called “Open-Architecture Composite Structure” or O-ACS. The O-ACS geometry is created from special composite yarns in a lattice that minimizes weightm, but maximizes stiffness and strength. Each strand of yarn within the tube is formed from T700 carbon that is secured by a protective jacket for all-weather durability and abrasion resistance. The jacket prevents cracking, which is common in filament wound handguards. It also prevents splintering, which is common in roll-wrapped handguards.
Not only does the Carbon Fiber handguard withstand the heat of sustained firing, it also rejects barrel heat faster than other handguards. Under sustained fire, the barrel will be cooler and the handguard will cool faster compared to any enclosed guard. This improves barrel life and decreases heat signature duration.
When it comes to strength, controlled laboratory tests confirm that the Carbon Fiber Handguard can support a force of 100 pounds in any direction, and 400 pounds along its length. This is far more than what even the most extreme users require.
The designers of Brigand Arms conducted field tests for each of their handguard configurations. They made sure to fire thousands of rounds in various conditions – including tortuous ones. The Carbon Fiber Handguards were then taken back to the lab and inspected to ensure that there were no flaws or cracks after the field tests. Dozens of iterations have led to the current braid design of the handguard. The result is a high-strength design is truly unique – so much so, it’s covered by a US patent!
