2a Xan Sc-rail 15" M-lok W/al Nut

The 2A Armament Xanthos SC-Rail 15" M-LOK with Aluminum Nut is a purpose-built handguard engineered for shooters prioritizing minimal weight without sacrificing structural integrity. At 0.81 lbs, this M-LOK rail delivers the lightweight performance 2A Armament is known for, combining the Xanthos platform's proven design with a slant-cut aesthetic that sets it apart from traditional rail profiles. The integrated aluminum barrel nut features 2A's proprietary 45-degree set screw mounting system, enabling fast, repeatable installation to the upper receiver without protruding fasteners that catch on gear or reduce ergonomics.

At 15 inches in length, the Xanthos SC-Rail occupies the mid-length handguard space, offering sufficient real estate for optic mounting, vertical grips, and accessory placement while maintaining a compact, controllable profile. The M-LOK slot system provides industry-standard compatibility with an extensive ecosystem of tactical accessories—lights, lasers, slings, and backup sights integrate without rail adapters. Aluminum construction balances durability against weight, a critical trade-off in precision builds where every tenth of an ounce matters for handling and follow-up shot control. The slant-cut design distinguishes this model within 2A's lineup, appealing to operators who value both functional aesthetics and uncompromised performance.

This rail suits AR platform builders focused on lightweight precision carbines, dedicated marksmen seeking minimal mass forward of the magazine well, and shooters who run extended shooting events where cumulative weight fatigue impacts accuracy. The Xanthos SC-Rail integrates seamlessly with 2A Armament's Xanthos-Lite receiver sets, though compatibility extends to any upper receiver with standard barrel nut geometry. Field-proven reliability and precision machining across 2A's platform make this an uncompromising choice for those who demand accuracy and handling in a single-package rail system.
