Description
The Arisaka Defense M-LOK Indexer is a compact, low-profile hand stop engineered to provide consistent hand placement and improved control. Developed as an M-LOK version of Arisaka’s Finger Stop (originally for Picatinny rails), the Indexer features a slim front-to-back profile with a slight radius across both faces. It is typically positioned between the index and middle fingers to allow a forward grip on the handguard while remaining out of the way when transitioning to kneeling or prone positions. The wider, flatter profile also functions effectively as a barricade stop or a forward limit on shorter handguards.
