The UTG Pro M-LOK AR-15 13 in. Super Slim Free Float Handguard delivers a precision-crafted, USA-designed upgrade for enthusiasts seeking modular versatility and durable performance, featuring a 13-inch, 3-inch M-LOK free-floating profile with a proprietary barrel nut design that maintains a slim silhouette while maximizing accuracy. With 42 M-LOK slots across seven tracks, it provides abundant mounting options for rails and accessories, while the 31-slot top Picatinny rail offers a continuous, flush-fit surface on a flat-top AR-15 upper for optics and additional gear. Designed for standard Mil-spec AR-15 uppers, this handguard stays lightweight yet robust, made from precision-machined 6061-T6 aluminum and finished in a matte black hard coat anodize, ensuring resilience in demanding conditions. It includes two M-LOK accessories, an eight-slot Picatinny rail section, and a QD sling swivel adaptor, promptly ready for use out of the box, along with anti-rotation tabs that align accurately with the upper and prevent rotation under heavy use. Its ergonomic octagonal profile with grooved surfaces, scalloped top rail edges, and simple installation with included tools make it a practical, user-friendly enhancement for fast handling and customizable configurations.
