Faxon Firearms Streamline Carbon Fiber 17'' M-Lok Handguard Black

The Faxon Firearms Streamline Carbon Fiber 17" M-Lok handguard brings genuine weight savings to your AR-15 build without sacrificing strength or modularity. Carbon fiber construction delivers a stiffer, lighter platform than traditional aluminum—a meaningful advantage when you're running a precision rifle, competition setup, or any build where maneuverability matters. At only 8 ounces on the 15" variant, this handguard keeps your rifle nimble while maintaining the rigid interface your optics and accessories demand.

Eight full-length M-Lok slots run the length of the handguard, giving you complete flexibility to mount lights, foregrips, sling attachments, and other tactical hardware exactly where you need them. The carbon fiber material naturally transfers less heat than aluminum, which is a real comfort benefit during extended shooting sessions when your barrel gets hot. Inside diameter clearance is generous enough to accommodate common suppressors if you're running a can under the rail. Installation uses a standard AR-15 barrel nut, so any builder familiar with drop-in handguards can swap this on without special tools.

When installed correctly, the Streamline locks in across all three axes, creating a stable, repeatable platform that won't shift during recoil or heavy use. Whether you're building a long-range hunter, a 3-gun competition rifle, or a duty-focused AR, this handguard delivers the weight savings of carbon fiber with the accessory mounting versatility serious shooters expect.
