Magpul Index Stop Features The Magpul Index Stop is a small hand stop designed primarily for the index finger giving the shooter a consistent safe reference point that maximizes comfort and control over the support hand. By establishing this physical reference point the Index Stop helps reduce the risk of the support hand creeping forward past the muzzle during use. Ridged texture on both the front and rear surfaces improves grip even under recoil or when hands are sweaty or gloved. Its ambidextrous design means it works equally well regardless of which hand the shooter uses to support the rifle. Built to the same dimensions as Magpul s Type 2 M-LOK Rail Covers with a 1/8 inch protrusion from the rail surface the Index Stop integrates seamlessly alongside other M-LOK accessories for a clean cohesive handguard layout. It is molded from Magpul s proprietary polymer and finished in Flat Dark Earth with a matte texture matching a wide range of rifle color schemes. Compatible specifically with octagonal aluminum M-LOK handguards it mounts quickly using minimal rail space while still providing a dependable reference point. Weighing just half an ounce the Magpul Index Stop adds functional control to an M-LOK handguard without any meaningful weight penalty.
