With a lot of cans having some zero shift from removing and installing suppressors what do you guys do when you want to clean the barrel? My Flow 5.56K has a slight zero shift so part of me wants to leave it in and just run the cleaning rod through it but then I'm afraid it'll get carbon locked if I never remove it.

I don't shoot regularly so I like to clean my guns after each session.

My recommended item is breakthrough suppressor cleaner. I use it to clean everything from the barrel, bolt and inside the carrier. The stuff is literally the most amazing thing I ever used. I know you heard that dozens of times but I thought wipeout bore cleaner was amazing but this stuff blows it out the water.

It takes about 3-4 hours to clean a suppressor and about 1-2 hours to clean out the bore and bcg but if you can wait you’ll see this stuff is amazing. You’ll still need to pick and brush a little but nothing like originally.

I take the can off.
Zero shift should be repeatable.
If you're doing something (ex:  DMR match) where you really need a super precise zero, I would just verify right before with the same batch of ammo you'll be using for the activity, as should be standard procedure anyway.

It's believed by many that Breakthrough Suppressor Cleaner is made up of:

90–95% water

2–5% ethanolamine

3–5% 2-butoxyethanol

0.5% to 2% EDTA

…it means that in every 100 mL or 100 g of the final product, you'd have:

~2–5 mL/g of ethanolamine

~3–5 mL/g of 2-butoxyethanol
and so on...

This is not saying "2–5% strength ethanolamine solution was added" — it means pure ethanolamine comprises 2–5% of the entire solution.

I worry almost none about zero shift taking the suppressor off. I do worry about a patch getting trapped in a non-servicale can. That's a path to a baffle strike.
