Carry Comp muzzle rust

[AH64DB2]

Purchased in JAN, a couple hundred rounds, has never seen rain, stored indoors and it appears that there is rust in the muzzle. I just sent S&W and repair request. Has anyone else seen this?

Steel rusts. Just clean it off.
Most all carry guns get some at some point.

There is no SS used in firearms that has a high nickel content. Therefore..it will rust when the conditions are right.
