I'm doing my first AR15 build. I looked online for how to build an upper and the general consensus is to use Aeroshell 33 on the barrel nut. I've looked for it online and it only comes in tubes or tubs, far too much for what I need. Classic Arms has a nice small container of it, but they want over $15 shipping for something priced $4. Anyone here in NWI willing to share some?
PS
Any other alternatives to this stuff?
Don't overthink it man. That rifle will never know or care what lube you used on the barrel nut.
