Magpul Industries M-LOK Index Stop OD Green Polymer Hand Stop

The Magpul M-LOK Index Stop is a compact, minimalist hand stop purpose-built for octagonal aluminum M-LOK handguards. Designed primarily to seat the shooter's index finger, this low-profile accessory provides a repeatable reference point that locks the support hand into a consistent position for improved recoil management and faster follow-up shots.

Injection-molded from high-strength polymer and finished in a non-reflective matte OD Green, the Index Stop mounts directly into a half M-LOK slot and protrudes just 1/8" from the rail surface - keeping the profile snag-free and compatible with virtually any modern shooting grip. The front and rear faces carry a ridged texture for positive finger placement and added comfort under recoil, while the symmetric, ambidextrous design drops into either side of the rail with equal effect. At just 0.35 oz, it adds virtually no weight to the build.

Built to the same dimensional standards (1/8" protrusion) as Magpul's Type 2 M-LOK Rail Covers, the Index Stop is an easy, lightweight way to add an indexing reference without the bulk of a full-length hand stop. It pairs cleanly with other Magpul M-LOK accessories in matching OD Green and is a natural fit for competition rifles, defensive carbines, and hard-use duty builds alike.
