The Arisaka Defense M-LOK Indexer Forward Grip is a patented, low-profile hand stop designed to give AR-15 shooters a consistent, repeatable grip index point without the bulk of a traditional vertical foregrip.
- Patented indexer design slots naturally between index and middle finger for repeatable control
- Slim front-to-back profile keeps the handguard snag-free during transitions
- Slight radius on both faces reduces hotspots and improves long-session comfort
- Placed further forward on the handguard to stay clear in kneeling and prone positions
- Wider, flatter profile aids in pulling the rifle firmly into the shoulder
- Direct M-LOK attachment — no adapters required for most modern handguards
Who This Is For
The Arisaka Indexer is built for AR-15 shooters who run a C-clamp or thumb-over-bore grip and want a positive reference point without a bulky foregrip getting in the way. It's equally at home on a competition rifle, a duty carbine, or a home-defense build — anyone who prioritizes a clean, low-snag handguard profile while still wanting tactile feedback and improved muzzle control will appreciate what this small accessory delivers.

Frequently Asked Questions
How is the Arisaka Indexer different from a standard vertical foregrip?
Unlike a full vertical foregrip, the Arisaka Indexer is a minimal hand stop intended to sit between two fingers — typically the index and middle finger — rather than being gripped with the entire hand. This keeps it completely out of the way during positional shooting and maintains a slimmer, snag-free handguard profile while still giving you a consistent tactile reference point and improved ability to pull the rifle into your shoulder.
Will this fit my M-LOK handguard without any adapters?
Yes. The Arisaka Defense M-LOK Indexer is designed for direct attachment to any standard M-LOK compatible handguard. No adapters or additional hardware are needed. It is not compatible with KeyMod or Picatinny/Weaver rail systems — if you run a Picatinny rail, Arisaka Defense offers a separate Finger Stop designed for that interface.
Where on the handguard should I position the Indexer for best results?
Arisaka Defense recommends mounting the Indexer further forward on the handguard — closer to the muzzle end than you might position a traditional hand stop. This placement leverages the physics of a longer lever arm to help control muzzle rise more effectively, and it naturally moves out of the way when you shift your support hand rearward in kneeling or prone positions. Experiment with M-LOK slot placement to find what works best for your arm length and shooting style.
