The Ultimate Lightweight M-LOK Handguard In Carbon Fiber
Faxon Firearms is proud to offer the popular Streamline AR-15 handguard in carbon fiber for the ultimate lightweight and durable build. This M-LOK handguard maximizes the carbon fiber’s unique rugged characteristics which are 10x stronger than aluminum but 40% lighter.
The rail features complete M-LOK facets for mounting accessories and uses standard AR-15 barrel nuts for mounting to the rifle – driving weight down while maintaining decades-proven mounting systems. Optional accessories are available for shooters to maintain a co-witness of optics and accessories.

Reduces The Heat Of The Upper Assembly
The Streamline Carbon Fiber handguard also reduces the amount of heat transfer from barrel to handguard keeping your hands safe during long strings of fire. With the steel barrel nut and locking system, this free float handguard locks tight to your receiver without fear of it coming loose.
This handguard is also a great option for competition or duty us that will keep the weight of your rifle down, making it significantly more maneuverable.
Start building your ultimate lightweight AR-15 with the Faxon Firearms Streamline Carbon Fiber handguard.

- Extreme lightweight without sacrificing strength, rigidity, or practicality.
