The Arisaka Defense Finger Stop for Keymod rails in black (Arisaka part no. FS-K) brings Arisaka’s low-profile, patent-pending Finger Stop design to Keymod-equipped handguards. Rather than sitting at the rear of the support hand like a traditional hand stop, the Finger Stop is built to be positioned between the index and middle fingers, which typically places it further forward on the handguard. That forward position keeps it clear of the support hand when transitioning to kneeling or prone shooting positions.

Key Specifications

• Uses Arisaka’s low-profile, minimal-control design that adds little bulk to the handguard.
• Mounts directly to Keymod rail systems without needing an adapter.
• Positions between the index and middle fingers for a precise, repeatable index point.
• Forward placement keeps it clear of the support hand when transitioning to kneeling or prone.
• Functions as a forward limit, helping prevent fingers from slipping onto a hot barrel or suppressor.
