Build up in between a2 flash hider and muzzle

[spyderchop]

Hello, is it normal to have a small amount of greenish black build up between a2 flash hider and muzzle?

Just tried to scrap off but is tough as hell.

Like...carbon green?

Because yes, carbon build up is common on the muzzle face inside the flashhider.

Yes I guess it would be carbon green. It's tough to get rid of..any tips?

Ignore it. Scraping carbon will ruin the crown.

You don't need to worry about scraping the bolt, either. Anything that won't come off with solvent and normal cleaning materials (e.g. brush, paper towel, q-tip, etc.) doesn't need to come off that badly. The military mindset of cleaning everything to a white glove, as-new state is how you end up with more guns damaged from improper cleaning than worn out from shooting.

Also, the green colour you are seeing is from copper.

They are also made to sweep dirt parking lots too.

Doesn't make it a good idea

Jesus feck, don't do that. I'm sure his staff were arseholes as that's the first I've ever heard it in my 10 years. I'd catch flack just for taking the trigger out, the gas tube gets wiped off and that's all.
