The Arisaka Defense Finger Stop for M-LOK rails in FDE (Arisaka part no. FS-M-FDE) is a patent-pending, low-profile control that gives the support hand a precise index point rather than a bulky hand stop. Unlike a traditional hand stop positioned at the rear of the support hand, Arisaka’s Finger Stop sits between the index and middle fingers, which typically places it further forward on the handguard. That forward placement keeps it out of the way when transitioning to kneeling or prone, where most shooters move their support hand rearward.

Key Specifications

• Forward placement keeps it clear of the support hand when transitioning to kneeling or prone positions.
