The Patent Pending Arisaka Hand Stop is a continuation of their low profile, minimal control accessories. The primary goal of this accessory is to aid the user in pulling their rifle into their shoulder, enhancing control and recoil mitigation. The Hand Stop can also be used as a barricade stop, or reversed and placed at the front of the handguard to prevent the support hand from slipping off the end. The size and profile were designed to fit a wide variety of hands without being too large to get in the way. Height: 1.3" Width: 0.625" at widest point. Length: 1.4" Weight: 0.8 oz The Hand Stop is CNC machined from 6061-T6 aluminum and MIL-A-8625 Type III hard coat anodized. Requires an IP20/T20 Torx wrench for installation (not included).
