EXO coatings are Legit!

I think Jared @ Harsh Firearms has done the microslick coating, even on some pistons for high performance engines, might try him.

Thanks for sharing. That is impressive.

My Grendel has a Fail Zero bcg....other than being shiny I dunno whether it was worth the extra cash.

I agree that it may not be worth the extra cash (but most of the stuff I have isn't worth the extra $$$)

It replaced the Young NM BCG which is roughly the same amount, so it wasn't a price difference either way...

Just a follow up: I went and shot 50 rounds suppressed (lots of blowback with a can) it covered the BCG and I let it sit until I got home...

Running it completely dry, I had zero issues and the BCG wiped off EASILY with a dry paper towel. Looks mint with 20 seconds of wiping and stuck back in with zero lube.

Seems to be the best coating I've seen.
