The Slate Stop is a versatile drop-in, screw-on hand stop designed for any grip, rail, or M-LOK-compatible surface. Its unique, multifaceted geometry offers multiple methods of hand placement, improving recoil control, barricade stability, and comfort during carry and movement when the firearm is not actively employed. Shaped with input from military and competition shooters, the angles and contact points are optimized to reduce forward-hand slip and provide predictable indexing ahead of the muzzle. Constructed for durability, the Slate Stop features full M-LOK lugs, steel mounting hardware, and a high-temperature-resistant material that holds up in demanding environments. The Slate Stop mates directly with Slate Grips panels to produce a cohesive grip profile and low-profile footprint, delivering a reliable, adaptable solution for improved support-hand ergonomics across a wide range of platforms.
