The Magpul M-LOK Index Stop is a minimalist hand stop that gives your support hand a precise, repeatable reference point on octagonal aluminum M-LOK handguards. Molded from Magpul’s proprietary high-strength polymer with a ridged front and rear surface, it delivers secure finger indexing while keeping weight and bulk to an absolute minimum. Its half-slot footprint preserves valuable rail space and mounts directly to M-LOK slots without the need for adapters.

This compact index stop is ideal for shooters who prefer a straight-thumb or modern support-hand grip and want a low-profile solution to improve control and comfort while helping prevent the hand from creeping too close to the muzzle. It integrates cleanly with Magpul Type 2 M-LOK Rail Covers and works equally well for left- or right-handed users. Whether you’re setting up a lightweight carbine, a competition rifle, or a training-focused build, the Index Stop reflects Magpul’s reputation for smart design and durable, shooter-focused accessories.
