The correct greasing of aluminum AR pattern receiver threads is critical to avoid galling damage during the assembly of the rifle. Once installed, the grease further protects the threads from corrosion and seizing throughout the firearm's service life. Aeroshell 64 (formerly 33MS) is a MIL-G-21164D compliant grease, the only standard permitted to be used in the assembly and maintenance of military M16 and M4 pattern rifles and carbines. Long lasting, high load bearing, temperature and water resistant, Aeroshell 64 will stubbornly adhere to your rifle ensuring problem-free assembly and effortless maintenance.
Should be applied to the threads of the upper receiver, barrel nut, lower receiver and receiver extension during rifle assembly to prevent galling damage
