Hey guys, just curious, how often, if at all, are you guys removing your muzzle devices and cleaning your muzzle crowns? I've had a few barrels that showed a discernible difference with a cleaned crown after about 600 rounds or so, and a few where I couldn't ever really tell if it helped or not. Thoughts?

Cleaning muzzle crown..

Whenever the crust builds up enough to encroach on the crown really. That's going to depend high upon to many variables to generalize with a round count really.
Different powders, unsuppressed versus suppressed, muzzle device design, etc.
My TBAC brakes do a good job at keeping the crown clean. KAC, not so much. Factory AI brakes leave a little crust after 200 rounds or so. I think it's something you'd just have to gauge on a case by case basis.

I dont ever mount anything permanent on muzzle..i like to clean my crown by hand after removing brake
My crowns seem to get crap caked on them fairly quickly shooting suppressed. Hard to say how many rounds. When I pull he suppressor off to clean the barrel, there it is. Havnt noticed if this affects accuracy since I clean my whole upper when I clean the crown.
I do know the best way to clean it off though....
Take the upper off and prop it up with the muzzle in a plastic cup of CLR. About 1 inch of CLR is good. Then just wipe it off with a rag after 5 min. For large amounts of build up you may have to do this a few times. Beats the shit out of trying to get it off with a brush and bore cleaner. Just make sure you stand your upper up in a way that it won’t fall over.

The crud is going to build up on whatever serves as the crown.
Maybe a perforated disk (i.e. washer) seated snugly between the suppressor and the actual barrel could serve to collect the crud and preserve the actual barrel's crown. Having several could allow one to be soaking in solvent, another on the rifle itself, and another handy in reserve, and save downtime as well.
Just a thought.

Ummmm. No. The crown is always going to serve as the crown. A washer is gonna sit between the barrel "shoulder" and the supressor. Carbon never builds up there, just on the crown. Also, any washer there isnt a great idea. Adds another variable to barrel harmonics.
I don't do it every time, but you may need to do it the first time you pull your brake off of whatever rifle you're wanting to clean. I normally just get them hand tight and grab a rubber strap wrench and give a quick pull on it to get it just past hand tight.
