Dig having a light 3.6oz Handguard? Check the Brigand Arms Carbon Fiber Handguard that the Late Boy Scout reported during the SHOT Show. It is minimalist and those who usually mount more weapons accessories may not like it but for those who want a lighter weapon, this is a god-send. Below is what Brigand Arms says about their Patented Carbon Fibre 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."
