Arisaka Finger Stop
The Arisaka Finger Stop was designed for several different models and is a low profile, minimal control accessory. Unlike a hand stop, which most people position at the rear of their support hand, the Finger Stop 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 hand guard, 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-T6 aluminum and MIL-A-8625 Type III hard coat anodized. Requires a 5/32″ Allen wrench for installation (not included).
Per the ATF, installing an Arisaka Finger Stop on the forward accessory rail of a pistol will not result in the firearm being classified as an “any other weapon” as defined in the NFA, 26 U.S.C. § 5845(a).
