The XTS AR-15 2-Piece Quad Rail Black, model MT021, is a precision-engineered handguard designed to upgrade standard AR/M4 platforms with a stable, four-rail mounting surface. Machined from true 6061 aircraft-grade aluminum and finished with a hard-coat anodizing, it offers a durable, lightweight foundation for lights, lasers, grips, and other accessories while maintaining a streamlined profile for confident handling.

This two-piece design installs vertically without the need for gunsmithing, making it a practical choice for shooters who want to enhance their rifle’s ergonomics and accessory options. Available in carbine-length configurations, it supports range use, training, and general-purpose shooting where accessory placement and heat management matter. The MT021 reflects XTS’s focus on thoughtful design and reliable craftsmanship in modern AR accessories.
