The Arisaka Finger Stop is a low-profile, minimalist control accessory designed for 1913 Picatinny rails.

With its slim, ergonomic profile, the Finger Stop is intended to be placed between your index and middle fingers, positioning it further forward on the handguard. This placement ensures it doesn’t obstruct transitions to kneeling or prone shooting positions, where the support hand often moves toward the rear. Its wider design also functions effectively as a rear hand stop for those who prefer it in that position.

Additionally, the Finger Stop serves as a forward limit, preventing your fingers from slipping off shorter handguards onto a hot barrel or suppressor, and it doubles as a sturdy barricade rest.

The Finger Stop attaches securely to the rail with two nylon-tipped set screws (torque to 15 inch-lbs). Due to its low-profile design, installation requires sliding it onto the 1913 Picatinny rail. The fit is precisely machined to the 1913 Picatinny specification, so out-of-spec or damaged rails may pose challenges during installation.
