Perfection by PacificRainDog, August 25, 2021
This is my go to for pistols. Perfectly contoured and deburred. Thick anodizing. Longer than most hand stops that allows you to index between your index and middle finger. Tall enough to work on barricades. Oversized torx screws. Literally everything...

A great Indexer/stop by Sal Cappuccino, Verified Owner, September 24, 2021
This is my second Arisaka indexer and I have to say, as usual, I am not disappointed. I have this one and the smaller, more rounded indexer. This one is on a DD pistol and the smaller one is on a Rattler. Arisaka’s machining is top notch and it looks...

Product Info for Arisaka Defense M-LOK Indexers

The Patent Pending Arisaka Indexer is a continuation of our low profile, minimal control accessories. It was developed due to end-user demand for an M-Lok version of our Finger Stop for Picatinny rails, and features a slim front-to-back profile and slight radius across both faces.image

The Indexer can be used in a variety of ways, but the main intent is to place it between two fingers (usually index and middle). This typically places it further forward on the handguard, which also means it doesn't get in the way when transitioning to kneeling or prone shooting positions, where most people move their support hand towards the rear. Used in this manner, the Indexer makes it much easier to pull the rifle into your shoulder and maintain control while shooting.

Additionally, the wider, flatter profile of the Indexer functions very well as a hand stop or barricade stop, and also works as a forward limit to prevent your fingers from slipping off shorter handguards onto a hot barrel or suppressor.
