The Samson Keymod Evolution AR-15 15" Rail is a premium free-floating handguard designed to enhance the performance and handling of any AR platform rifle. Crafted from high-grade 6061-T6 aluminium and finished with MIL-A-8625 type III class 2 anodising, this 15-inch rail delivers an exceptional combination of strength, durability, and lightweight construction, making it an ideal upgrade for 3-Gun competitors, military and law enforcement professionals, or dedicated civilian shooters.
The Evolution Series is built for versatility, allowing shooters to customise their setup with removable accessory Picatinny rails (sold separately) that can be mounted at seven different positions and at any point along the rail’s length. The rail also features a continuous 1913 Picatinny top rail, providing ample space for optics and accessories, while integrated anti-rotation tabs ensure a secure and stable installation.
With an inner diameter of 1.56" and outer diameter of 1.80", the design is relieved to accommodate most gas piston systems and does not require the removal of the front sight base, offering greater installation flexibility. The inclusion of thermal bushings allows the handguard to clip easily to any Mil-spec barrel nut, maintaining a rock-solid free-float platform for improved accuracy.
