  • The use of an AR action block, receiver block insert, gas tube alignment tool and quality armorer's wrench is recommended for barrel installation.
  • Due to the manufacturing process, small burrs may occur inside the bore near the gas port. It may be necessary to run a cleaning patch through the bore to clear this burr before use.
