The primary purpose of this accessory is to help users pull their rifle firmly into the shoulder, improving control and reducing recoil. The Hand Stop can also function as a barricade stop or be reversed and positioned at the front of the handguard to prevent the support hand from slipping off. Its size and profile are carefully designed to accommodate a wide range of hand sizes without being overly bulky or obstructive. **Requires an IP20 TorxPlus driver for installation (not included).
