The Magpul M-LOK Index Stop delivers a compact, minimalist hand stop solution for shooters who want a precise, repeatable support-hand reference on their M-LOK handguard. Designed to occupy only half of an M-LOK slot, this low-profile stop protrudes just 1/8" from the rail surface and aligns seamlessly with Magpul Type 2 M-LOK Rail Covers. Molded from Magpul’s proprietary polymer and finished in Modified Coyote Brown, it offers a secure, textured surface that helps prevent the support hand from creeping too close to the muzzle.

This ambidextrous index stop is purpose-built for octagonal aluminum M-LOK handguards, giving both left- and right-handed shooters a consistent anchor point without adding unnecessary bulk. Its ridged front and back faces enhance grip and control, making it well suited for range use, training, and general-purpose shooting where comfort and repeatability matter. Backed by Magpul’s reputation for durable, user-focused design, the M-LOK Index Stop is a simple upgrade that refines how your rifle handles.
