Saw this post on Facebook recently and figured I'd see what everyone's thoughts are. They claim it's from not removing the "moderator" when storing, other context indicated somewhere in EU. I know the S2H classes shoot a ton in cold weather and it's been mentioned many times that cans get screwed on for the life of the barrel and run with no issues. Just wondering what would cause it to get THAT bad?

That one has been debunked on multiple sites. LRH I believe has a rather long post about it.
 
Do suppressors increase carbon buildup? I believe so. But that bolt face?! Looks like a dude was shooting black powder and pointed the muzzle up and hit the butt on the ground after every shot for a long time! Somethin funny going on to get buildup like that.

I store them muzzle down but that’s about it.

That one being the concept of taking the can off when storing makes a difference, or that specific case they posted about? They posted those within the last 1.5 months so I figured it was recent, if they're reposting old pot stir stuff that's just dumb.

Yeah, it's wild. I get not cleaning, hell I'm testing that myself. But to neglect a bolt face to that extent seems like something was intentional.
 
I take my can off for storage.

Most of the time it’s just carbon, but mix heat and humid cold weather and it hasn’t been uncommon for me to pull a suppressor off to find what appears to be a wet surface on the muzzle or brake. Iv only ever seen this during times near or at freezing with a lot of humidity.

I also clean my suppressors so I’m not dealing with the constant flow of crap down my bore.
 
A lot of western shooters are so used to low humidity it freaks them out that stainless can actually rust and pit in the right conditions. Combustion of gunpowder creates all sorts of chemicals. As for the carbon flaking off the can and building up on the bolt face, that’s not news even to guys like me who don’t own one. It’s not a big leap in logic to assume some cans have carbon steel parts, or low quality stainless that rusts and rusty carbon flakes contribute to the rust color in the chamber. This is probably a farm/ranch coyote rifle with a cheap can kept vertical and bounced around every day in a side by side, tractor or jeep. It’s being a little dramatic of the guy taking the pics to not show the bolt face after being cleaned off with simple scrubbing, or not cleaning the chamber to only show pitting and not just the discoloring.

We just bought a case of Kleenex at Costco if anyone needs an extra box to get through this. You’ll be ok.
 
I don’t take my silencers off very often at all. I’m not even going to bother checking to see if this is going on with my guns because I know it’s not.
 
My suppressors come off the rifles every time they go in the safe. I store a lot of other things in my gunsafe and it's nice to keep the barrels shorter. I don't have POI shifts going on and off with the suppressors and I wipe the crown with CLP on a soft rag just to remove the gunk.

I do use one rifle that the suppressor stays on except for bi-annual inspections. Suppressors definitely make guns run dirty, but even after a couple thousand rounds in a gas gun shooting cheap ammunition and a few years no cleaning, I've never experienced parts as dirty as the tikka bolt face above. If you can, make sure to let your rifle air out and fully cool before casing it as I have seen suppressors create steam inside a gun case if not fully cool.
 
I borescoped my chambers, just a quick check. Everything looks good. I leave the suppressors on all season. Take them off for storage through the summer and clean up the rifles also.
 
I keep bolt faces clean and swab chambers out, I pulled my can off 223 and had some pretty good build up on the crown cleaned it all off. 200+ rounds.
I get not touching the bore if it’s shooting, I leave my mine alone. But I pull the bolt often and take a look down it. It’s to easy just to check on.

I dont know what’s going on in that picture but I saw it posted as well and thought there was something else going on.
 
Totally normal when shooting suppressed. My demo guns have carbon seeping from every seam imaginable.

Are you saying the erosion of that chamber is normal? I’d strongly disagree with you on that.

That's not what i am saying, after some hundreds of rounds. Carbon will build up for sure. Clean it up and go at it again.
