check picture and read Please... so I pick up the VLS in .308 today. I took pictures(ofcourse) and happened to take one from the front. I see something I didnt notice before, so I grab my mini mag and sure enough, I see brown marks at the muzzle end, only about 1/4" in length, and they just stop. You can see from the pic that they dont travel up the barrel. I dont remember seeing this before in rifles I had, but to be honest, I cant say I ever checked them or looked for such a marking. what could have caused this and should I return it or wont it matter? The rifling itself looks great, its just those patterns of brown marks. It rubbed at it with a cotton swab and its clean, nothing came off. I wont be shooting it until this weekend sometime. Im wondering if I should even bother incase it voids the return policy. any advice is greatly appreciated. Thanks... after further thought, I think it might be copper fouling. I guess ill get some hoppes bench in there and try and remove it.
