Hi all,
I noticed on my rifle today while cleaning it something I'd previously overlooked which is the crown.
Previously I just work the brush in and out so a thin ring of gunk has built up around the end.
Am I good to just use a scouring brush or something similar to keep that clean? Something abrasive but relatively soft?
I don't want to leave the ring in case of corrosion but don't wanna scratch up the crown by using the wrong thing either.
Advice?
