MDT 103572-BLK: 10.25" Blk M LOK ARCA Rail

The MDT ARCA Mount is a premium upgrade for any M-LOK compatible rifle chassis, specifically optimized for MDT’s ESS and LSS-XL Gen2 systems. MDT 103572-BLK attaches securely via the M-LOK interface and provides a generous 10.25 inches of mounting surface, allowing compatibility with a wide range of tripod adapters and shooting accessories. Fourteen precision-drilled and tapped holes enable consistent and repeatable accessory placement, while a rearward overhang brings the mounting point closer to the rifle’s center of gravity for improved balance on tripods. The mount features an angled front face to facilitate smoother tripod engagement and reduce snags, and its rounded edges enhance comfort during unsupported or offhand shooting. Each ARCA Mount is precision-checked to meet the stringent Really Right Stuff standard, ensuring top-tier performance and reliability.
