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. Low heat transfer for handing extreme duty cycles. Fits common suppressors under-railAttaches with standard armorer's wrenches and tools.Co-witness iron sights and optics/lasers* *Requires optional low-profile M-LOK rail adapters.  Specifications: 13” STREAMLINE CARBON, Standard Length: 13.3"Weight w/o Barrel Nut (Includes ALL Mounting Hardware): 6.12 Ounces Weight, Steel Barrel Nut: 1.28 OuncesWeight, Titanium Barrel Nut: .77 OuncesHeight (Flat to Flat): 1.98"Max Outer Diameter (Peak to Peak): 2.05"Max Inner Diameter (Front Aluminum Ring):  1.70"Construction: Lancer Carbon Fiber & Aerospace Aluminum - Type III Hard AnodizedAccessory Mounting: M-LOKM-LOK Slots: 7Attachment Method: Standard AR-15 Barrel Nut, Patent-Pending Clamp Architecture  ALL Include: Steel AR-15 Barrel NutSTREAMLINE Carbon Fiber RailAll Mounting Hardware
