From the manufacturer
Fusing Faxon's innovation and engineering with Lancer Systems' carbon fiber know-how, the STREAMLINE Carbon Fiber Handguard maximizes carbon fiber's unique rugged characteristics with practical application. The rail features 8 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. Carbon fiber is 10x stronger than aluminum and 40% lighter. We created a carbon fiber handguard that is competition and duty ready, weighing in at only 7.99 ounces, with a steel barrel nut! Optional accessories are available for shooters to maintain co-witness of optics and accessories and when combined with titanium barrel nuts, drive the weight for a practical 15" handguard below 8 ounces. Already proven on champion competition rifles, the STREAMLINE Carbon Fiber Handguard is rugged and ready for anything a shooter can throw at it. Features: Extreme lightweight without sacrificing strength, rigidity, or practicality.M-LOK attachment across 8 facets.Dramatically increases maneuverability of the weapon over metal rails.
