The Arisaka Defense Indexer M-LOK is a low-profile tactical rail accessory designed to improve grip, control, and shooting stability on M-LOK handguards. Built from 6061-T651 aluminum and hard coat anodized to mil-spec standards, this minimal-footprint finger indexer positions naturally between your index and middle fingers further up the handguard—exactly where you need support without interfering with transitions to kneeling or prone positions. Whether you're running a competition rifle, hunting platform, or duty gun, the Indexer delivers the kind of thoughtful design that solves real shooting problems without adding bulk or weight.
The Indexer works multiple ways. Primary use places it forward on the rail to give your support hand a positive index point, making it significantly easier to pull the rifle into your shoulder and maintain consistent control through recoil and target transitions. The wider, flatter profile also functions effectively as a hand stop to prevent your fingers from rolling onto a hot barrel or suppressor, and as a barricade stop when shooting from support. Its slim front-to-back footprint keeps it out of the way whether you're running a short handguard or working around other accessories.
Installation is straightforward: the Indexer mounts via two M-LOK nuts and 10-24x5/16" Torx button head screws (an IP20/T20 Torx wrench is required but not included). At just 0.6 ounces, it adds no meaningful weight or complexity to your setup. It's the kind of purpose-built accessory that makes sense only if you've shot enough to understand the difference a proper hand index makes.

| Mount Type | M-LOK |
| Material | 6061-T6651 Aluminum |
| Finish | MIL-A-8625 Type III Hard Coat Anodized |
| Height | 1.0" |
| Width | 0.58" |

| Hardware | Two M-LOK nuts and two 10-24x5/16" Torx button head screws |

The Indexer is primarily designed to be placed between your index and middle fingers on the handguard, providing a natural reference point that improves your ability to control recoil and pull the rifle consistently into your shoulder. It also works as a hand stop to prevent finger slippage onto hot barrels or suppressors, and as a barricade stop during barrier shooting.
This M-LOK version mounts to any M-LOK handguard using standard M-LOK slot spacing. It does not fit KeyMod or Picatinny rails; Arisaka makes separate versions for those standards.
You'll need an IP20/T20 Torx wrench to install the two Torx button head screws. The wrench is not included with the accessory.
The M-LOK Indexer weighs just 0.6 ounces, making it negligible in terms of overall rifle weight or balance.
