Single-piece rifle tube spacer that combines the functions of a Spring Booster and Rifle Tube Spacer for an approved AR-15 H3 buffer and L6 Black Spring configuration.

The Kurt Spacer is a single-piece component that replicates the combined function of a Spring Booster and Rifle Tube Spacer. It is designed for use inside a 9.68-inch rifle receiver extension with the AR-15 H3 buffer and L6 Black Spring configuration shown on the Lima Six buffer system chart.

By combining both functions into one component, the Kurt Spacer establishes the required internal spacing while applying the intended preload to the L6 Black Spring.

Use the Kurt Spacer only in the configuration shown on the Lima Six Buffer System Configurations chart. Do not combine it with a separate Spring Booster or Rifle Tube Spacer unless specifically instructed by Lima Six.
