The Arisaka Defense Arisaka Indexer M-Lok FDE is a compact, low-profile hand stop and finger indexing accessory designed to give shooters a more consistent and secure support-hand position on their rifle. Machined from 6061-T651 aluminum with a slim front-to-back profile and gentle radius on both faces, it mounts directly to a single M-Lok slot and includes two M-Lok nuts and Torx screws for a solid, repeatable installation.

Used between the index and middle fingers, the Indexer naturally positions the hand further forward on the handguard, helping the shooter draw the rifle into the shoulder and maintain control during strings of fire or position changes. Its wider, flatter face also works well as a hand stop or barricade stop, and serves as a forward limit to keep the support hand from sliding onto a hot barrel or suppressor. Finished in Flat Dark Earth, it integrates cleanly with modern AR-15 builds and reflects Arisaka Defense’s focus on practical, well-executed accessories.
