One Horse M-LOK Slim Design 15" Handguard Lightweight, Low-Profile AR-15 Rail System The One Horse M-LOK 15" Handguard elevates AR-15 builds with a sleek, lightweight design that provides ample mounting space while maintaining a low profile for enhanced handling. The slim profile delivers comfortable grip and reduced weight without sacrificing accessory mounting capability. Featuring M-LOK slots for secure, modular attachment of grips, lights, optics, and other accessories, this handguard offers versatility for tactical, competition, or general-purpose setups. Crafted to Mil-Spec standards with durable hardcoat anodized finish for exceptional corrosion resistance and rugged durability. Includes steel barrel nut and mounting hardware. Made in the USA. 15" Length for Extended Mounting Options The 15-inch length provides extended rail real estate for mounting multiple accessories while improving barrel coverage. This length accommodates mid-length and rifle-length gas systems, offering flexibility for various barrel configurations. The extended handguard protects the shooter's support hand from barrel heat during extended firing sessions while providing forward mounting positions for lights, lasers, and grips. Slim Profile Design The slim profile design reduces overall handguard diameter for comfortable grip and improved weapon handling. The low-profile construction minimizes bulk and weight compared to quad-rail systems while maintaining structural rigidity. This slim design proves especially beneficial for shooters with smaller hands or those preferring a more streamlined firearm profile. M-LOK Modular Mounting System M-LOK slots provide secure, modular attachment points positioned along the handguard for accessories including vertical grips, hand stops, flashlights, laser aiming devices, bipods, and sling mounts. The M-LOK system enables precise positioning of accessories exactly where needed while keeping unused sections slim and snag-free. M-LOK accessories attach directly to the slots without requiring continuous Picatinny rails, reducing weight and bulk. Steel Barrel Nut The included steel barrel nut provides robust attachment to the upper receiver with superior strength compared to aluminum barrel nuts. Steel construction withstands the high torque required for proper installation and maintains secure lockup through thousands of rounds. The barrel nut includes all necessary mounting hardware for installation. Mil-Spec Construction Crafted to Mil-Spec (Military Specification) standards, the handguard meets rigorous dimensional and material requirements for AR-15 platform compatibility. Mil-Spec construction ensures proper fit with standard AR-15 upper receivers and compatibility with standard AR-15 components. Hardcoat Anodized Finish The hardcoat anodized finish provides superior wear resistance and corrosion protection compared to standard anodizing. This Type III anodizing process creates an extremely hard surface layer that resists scratching, abrasion, and environmental exposure. The black finish maintains appearance through extended use while protecting the underlying aluminum. Lightweight Construction Despite its 15-inch length and robust construction, the slim design and aluminum construction keep weight manageable. The lightweight handguard reduces overall firearm weight, minimizing fatigue during extended shooting sessions or carries. This weight reduction improves handling and maneuverability without compromising strength or durability. Free-Float Design The free-float design attaches only to the barrel nut, eliminating contact with the barrel. This design prevents accessories, grips, or external pressure on the handguard from affecting barrel harmonics and point of impact. Free-floating the barrel improves accuracy potential compared to handguards that contact the barrel. Versatile Application The 15-inch M-LOK handguard suits tactical applications, competition shooting, hunting, and general recreational use. The modular mounting system adapts to different mission requirements simply by adding or removing accessories. This versatility makes the handguard suitable for duty rifles, 3-gun competition, precision builds, and general-purpose carbines. Made in the USA Designed, engineered, and manufactured in the United States, the One Horse handguard represents American manufacturing quality and craftsmanship. The One Horse M-LOK 15" Handguard delivers slim, lightweight design with modular mounting capability-an excellent upgrade or build component for AR-15 rifles.
