The Arisaka Finger Stop M-LOK (unlike a hand stop which most people position at the rear of their support hand) has a rounded profile which is ergonomically designed to be located between your index and middle fingers. This typically places it further forward on the handguard, which also means it doesn’t get in the way when transitioning to kneeling or prone shooting positions, where most people move their support hand towards the rear.

Additionally, the Finger Stop functions well as a forward limit to prevent your fingers from slipping off shorter handguards onto a hot barrel or suppressor, and as a barricade rest.

The Finger Stop is CNC machined from 6061-T651 aluminum and MIL-A-8625 Type III hard coat anodized. Requires a 5/32″ Allen wrench for installation (not included).
Hardware: One M-Lok nut and one 10-24×5/8″ hex cap head screw.
