- Don’t build without itTore apart my first build and greased up the buffer and barrelnut. Probably could grease up whatever part you want to and I am greasing my latest build. Excellent protection. Messy as all Hell. Love it. A little does a lot and it works.
- So greasyBuy this it works!
- A little goes a LONG wayIt's terrific that TNA offers this product in a handy little container. It's essential to any AR build or project. Purchase with confidence, this stuff works.
Anti-Seize Thread Grease (Mil-spec Aeroshell 64, replaces 33ms) (1/8 oz)
Not your ordinary gun oil, this hard-to-find grease is a must-have for any successful AR-15 build.
Why not use ordinary grease or gun oil?
Your AR-15 uses screw threads to attach the Barrel Nut and Buffer Tube Castle Nut. While tightening, the thread surfaces slide against each other at high pressure. Even though the metal might look smooth to your eye, at a microscopic level there is a roughness. As these surfaces rub together, the metal can rip and tear (galling). The threads get gouged or possibly even stick together permanently (cold welding) making the threads impossible to separate without damaging one or both parts.
Aeroshell 64 is an extreme pressure (EP) grease which is specially formulated to prevent galling. With this grease in place, you will be able to easily assemble and disassemble your rifle with no thread binding, even after thousands of rounds and many weekends of abuse.
Under the extreme pressure of tightening the Barrel Nut or Castle Nut, ordinary liquid oils or greases get squeezed out and the parts touch each other, defeating the oil. And under the high temperature of firing your gun, greases can 'run' or evaporate.
How does it work?
Aeroshell 64 is a special blend of grease and molybdenum disulfide. The moly is a fine powder that bonds to the surface of the metal, so the moly rubs against itself rather than your gun's threads rubbing directly. And although the ordinary grease component may evaporate with the high heat of shooting your gun, the moly will stay behind.
AeroShell Grease 64 is an extreme pressure (EP) grease is based on lithium complex technology of AeroShell Grease 33, + 5% Molybdenum Disulphide.
AeroShell Grease 64 is the modern replacement for AeroShell 17 and AeroShell 33ms which were the original mil-spec barrel nut greases. More info can be found here.

Installation notes: You need to take your time and not make a mess with it during application, a little goes a long way. You can use a small brush from the dollar store or a Q tip.
Other notes: The product is repackaged by us into small plastic jars. The containers are a little oversized so expect some air inside the container. Contents may shift during shipping! We cannot offer guidance for aerospace use, but we can point you to AME's who can.
Difference between Aeroshell 33ms and Aeroshell 64? Our friends at Shell have renamed Aeroshell 33MS to Aeroshell 64. Why you say? It's because people were mistaking 33 for 33ms which is a BIG problem if you want things like your landing gear to meet manufacturers spec. So this ad and product is for the new Aeroshell 64 which is the new MIL-G-21164D compliant extreme pressure grease. See the picture section for a letter from Shell verifying these statements. Otherwise Aeroshell 33ms and 64 are the exact same stuff.
