Faxon AR-15 15″ Carbon Fiber M-LOK Handguard
The Faxon AR-15 15″ Carbon Fiber M-LOK Handguard blends Faxon’s forward-thinking design with Lancer Systems’ carbon fiber expertise to deliver a handguard that’s ultra-lightweight, incredibly strong, and built for high-performance shooting. The STREAMLINE Carbon Fiber Handguard offers shooters an advanced upgrade that enhances rifle maneuverability while maintaining trusted mounting compatibility with standard AR-15 barrel nuts.
Constructed with eight full M-LOK facets, this 15″ handguard provides extensive flexibility for mounting lights, grips, bipods, and other accessories exactly where you need them. The carbon fiber construction not only reduces weight dramatically but also offers superior heat resistance and durability for extended firing sessions. With a clean, low-profile design, it’s ideal for duty builds, competition rifles, and premium custom AR platforms.
By utilizing carbon fiber, which is 10x stronger than aluminum and 40% lighter, this handguard helps shooters achieve a better-balanced weapon system without compromising strength or rigidity. The included steel barrel nut ensures rock-solid installation using standard tools, and the internal profile is large enough to accommodate many suppressors for under-rail mounting.
Features:
- Exceptionally lightweight without sacrificing strength or durability
- M-LOK slots across 8 facets for versatile accessory mounting
- Enhanced maneuverability over traditional aluminum handguards
- Low thermal conductivity to reduce heat transfer during sustained fire
- Suppressor-compatible with common under-rail setups
