The Leapers MTU015SSM is a high-performance 10.52 (Mid-Length) quad rail handguard designed for the AR-15 platform. Precision-machined from 6061-T6 aluminum with a Matte Black hardcoat anodized finish, this 12.40 oz unit features a slim 1.37 internal diameter and a 2.44 width. It provides four permanent Picatinny rails at the 3, 6, 9, and 12 o'clock positions, offering maximum mounting real estate for tactical lights, lasers, and vertical grips. Engineered for durability, this drop-in rail system provides a rigid, non-rotating interface while maintaining a streamlined profile. Note: This Super Slim variant of the MTU015 series is significantly lighter than the standard version, weighing only 12.40 oz while still providing the full versatility of a four-sided Picatinny rail system.
