Product DescriptionThe Arisaka Defense Hand Stop is a compact, low-profile control accessory designed for 1913 Picatinny rails. Its primary purpose is to help you pull the rifle firmly into your shoulder for improved control and recoil management. It can double as a barricade stop, or be reversed at the front of the handguard to prevent your support hand from slipping off the muzzle end. A unique captured recoil lug and mating screw provide a secure, rattle-free lockup, and a CNC-engraved rotation indicator aids with tightening or loosening during installation. Lightweight yet durable, the Hand Stop is precision machined from aluminum and finished in hard coat anodize for long-term performance.Product HighlightsLow-profile hand stop enhances grip, shoulder pull, and recoil mitigationMounts directly to 1913 Picatinny rails; reversible to prevent hand slippageCaptured HS-P recoil lug and screw deliver secure, rattle-free lockupCNC-machined 6061-T651 aluminum with MIL-A-8625 Type III hard coat anodized finishCompact and lightweight at just 0.84 oz; Made in the USASpecsRail Compatibility: 1913 PicatinnyMaterial: 6061-T651 AluminumFinish: MIL-A-8625 Type III Hard Coat Anodized, BlackDimensions: Height 1.3"; Length 1.1"; Width 1.19" at Picatinny clamp, 0.625" at main interfaceWeight: 0.84 ozHardware: One 6-32 x 1/2" hex cap head screw; one HS-P recoil lugInstallation: 7/64" Allen wrench required; maximum torque 15 in-lbCountry of Manufacture: USAUPC: 850036188193Manufacturer Part Number: HS-PBrand Name: Arisaka DefenseDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
