Enhance your Glock 19 Gen 5 with the Mass Driver Compensator designed to optimize performance and accuracy. This innovative compensator utilizes expelled gases to function as a counterbalance effectively reducing mechanical recoil. Unlike traditional barrel-mounted compensators that can impact cycling reliability the Mass Driver separates from the operating components post-ignition maintaining near-stock cyclic speeds while minimizing reciprocating mass. This ensures smoother operation and improved handling without compromising the firearm's reliability. Included in the package are the compensator's main body recoil spring guide rod fitment washer guide rod head internal spring and a detailed warning card all crafted to elevate your shooting experience.
