Arisaka Defense Picatinny Finger Stop – Aluminum Black

The Arisaka Defense Finger Stop is a low-profile, minimal-control accessory engineered for 1913 Picatinny rails. Its slim, ergonomic shape is intended to be placed between the index and middle fingers, keeping the support hand forward without impeding transitions to kneeling or prone positions. The wider profile also allows use as a rear hand stop and provides a forward limit to prevent the hand from slipping onto a hot barrel or suppressor. The part is secured to the rail by two nylon-tipped set screws and must be installed by sliding onto a 1913 Picatinny rail to achieve the designed fit.
