Magpul Industries M-LOK Index Stop Coyote Brown Polymer Handstop

The Magpul M-LOK Index Stop is a low-profile hand stop built for shooters who want a repeatable support-hand index on M-LOK equipped handguards. Designed primarily as a reference point for the index finger, the Index Stop helps lock the support hand in the same position shot after shot, improving recoil management and trigger discipline on AR-pattern rifles, AR pistols, and other platforms running M-LOK rails.

This Coyote Brown Index Stop is molded from Magpul's proprietary polymer and installs with the included 4140 chromoly steel mil-spec hardware. It clamps directly into any standard M-LOK slot without permanent modification to the handguard. The Index Stop requires only a 1/2 M-LOK slot and is compatible with octagonal aluminum M-LOK handguards.

At just 0.35 oz and measuring 0.78" L x 1.04" W x 1.25" H, the Index Stop adds virtually no weight or bulk at the support-hand position, making it ideal for compact builds and rifles with shorter handguard real estate. It is particularly useful on PDW-style AR pistols, short-barrel rifles, and any platform where a defined gripping reference improves handling.
