Product DescriptionThe Strike Industries Mass Driver Compensator is designed for Glock 19 Gen 5 pistols to help attenuate felt recoil while maintaining near stock cyclic speed. Unlike traditional barrel-mounted compensators that can add reciprocating mass and negatively affect reliability, the Mass Driver Compensator uses hot gases expelled after discharge and separates from operating components after ignition to reduce reciprocating mass. This kit includes the necessary recoil system components for installation.Product Highlights Mass Driver (gas-driven) compensator design helps reduce mechanical recoil while supporting reliable cycling Designed for Glock 19 Gen 5 pistols and 9mm applications Helps maintain close-to-stock cyclic speeds by reducing added reciprocating mass versus barrel-mounted comps Complete kit includes recoil spring and guide rod components for fitment Black finish for a clean, integrated look Specs Brand: Strike Industries Product Type: Pistol compensator (Mass Driver Compensator) Compatibility: Glock 19 Gen 5 Caliber: 9mm Color: Black Included: Comp main body, recoil spring, guide rod, guide rod fitment washer, guide rod head, internal spring, warning card Manufacturer Part Number: G5MDCOMPC UPC: 793811765205 Disclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
