It is also recommended to apply a small amount of moly (molybdenum disulfide) grease to the receiver threads. Moly
grease is available at most automotive parts stores
The use of an AR action block, receiver block insert, gas tube alignment tool and quality armorer's wrench is

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.
