Samson KeyMod 4" Rail Kit Black Anodized - Lightweight Aluminum

The Samson KeyMod 4" Rail Kit transforms standard KeyMod slots into versatile Picatinny rail sections for tactical accessories. This black anodized aluminum rail segment provides secure mounting points for lights, lasers, grips, and bipods without adding unnecessary weight to the rifle platform.

What Makes This Different

Unlike bulky quad-rail systems, this modular KeyMod rail attaches only where needed, maintaining the rifle's balance and handling characteristics. The precision-machined aluminum construction delivers MIL-STD-810 durability while weighing just 1.2 ounces. The black Type III hard anodized finish resists corrosion and wear from repeated mounting and dismounting of accessories.
