Is this baffle erosion?

Using solvents to clean? Wear from stainless pins?

Kinda looks like galvanic corrosion/two metals reacting.

I use Water with dawn in my bath with the pins when I tumble them.

I don't have a single suppressor I can fully disassemble.

Centerfire it doesn't much matter, but rimfire it needs to be user serviceable...

Last pic looks eroded to me.


We will be building supressors this year. Members here will get a discount.

Send me details when youre un-banned.

My guess is the steel pins are wearing the aluminum baffles during the cleaning process. I use Hoppe's 9 and some elbow grease to clean mine.

Why was it only these 2 though, they've all spent the same amount of time in the tumbler?

Not saying you're wrong, just what I notice.

Yeah, I'm too OCD to let them go too long....

I don't know how many aluminum baffles we have in these cans. Keep us posted if the other baffles start showing signs of wear. My baffles aren't nearly as clean as yours, and I don't get to use my cans as much since the range down the street closed.

They are all aluminum except for the stainless blast baffle. Some are anozided black while others are a raw grey color.

That is not erosion.

My guess would also be damage from stainless steel pins, you don’t want to tumble anything aluminum in stainless steel.

However, it is odd that it is only appearing on certain baffles. Are you having to drive the baffles out of the silencer? I once saw a .22 silencer with kinda/sorta similar damage caused from pushing the baffles out of the can. Some carbon buildup damaged the baffles as they scraped together.

I wouldn’t worry about it, keep shooting and be a little more careful when cleaning.
