    We do complete bolt carrier groups with micro-slick for $50
    Here is a test with a dry bolt carrier on full auto

    Is the coating directly applied over the manganese phosphate on the BCG or are you coating BCG's in the white (ITW) like the one pictured?

    typically metal is media blasted for better adhesion. I dont think there is any reason to remove the gas key. bolts are stripped and gas ring grooves are masked .

    Typically .001.
    Hardness is 9 for micro slick

    Interesting, but not as interesting as coating the baffles and inside tube of a suppressor to simplify cleaning. Think the coating would survive and enable easier cleaning?

    Pencil Hardness (ASTM D3363) 9h

    This is a paint scratch test standard, not really a true hardness test. 9H is soft, and could be scraped off with a pocket knife. If one used this product to coat suppressor components, it would blast away in a few shots.

    I have tested coated inconel suppressor components with some high performance micro-films that register their hardness in the Vickers Scale. ( Super Hard ) It was blasted away in a few hours...

    How do you strip Cerakote off of parts if a mistake is made, or one wants to change the color?

    Cerakote can be stripped of by sandblasting with garnet sand. Pressure is adjusted for the type of material

    Does it help with getting them apart and/or cleaning? I’ve got a .22 can with stainless k-baffles that I’d like to test. 338 Win mag probably doesn’t build up much junk.

    The coating can be blasted off with a sandblaster and aggressive media, but will withstand repeated blasting from a firearm?? That seems to defy logic... lol

    The cores and tubes for the .22 rimfire clean pretty easily with standard cerakote. We will be testing microslick on them next week.

    I am thinking that the blast baffle will get stripped, but the rest of the baffle and the tube really get pressure and heat but not blasting.

    So I cerakoted a suppressor core with blue air cure cerakote and used the can when when i broke in a new 6.5 creedmoor barrel for my ruger precision. Here is what it looked like after 20 rounds.

    I wiped off some of the carbon to show the cerakote under the gunshot residue. I did this test with a blue color to make it easy to see the coating. Microslick is a dark grey and is hard to tell it apart from the gunshot residue in a picture. I will start a separate thread with more pics

    Interesting...! Good idea with the blue coloring. Thx for sharing.

    Will you be doing a 300-500+ round test of any kind? Higher round count would provide some more data for evaluation.

    I've been waiting for the OP to respond how long the Microslick will hold up but we haven't seen that yet. In my experience, it does not last very long on the contact surfaces such as the four rails on an AR bolt carrier or the side of a 10/22 bolt. It will last awhile on every other surface making cleanup easier. So for reduced friction, it's not worth it. But, for clean up it works great.

    here is the BCG with over 800 rounds on full auto with no lube and a suppressor. The machine gun makes the testing faster and i dont have any trouble finding people to help out :)

    yes , the microslick can transfer off, but you can stop by anytime and do a back-back test with a nickel boron bolt. Nickel boron will have failures, the microslick had none so far. Just bring the ammo :)
