Brocock/BRK Scratches on brand new gun barrel?

That 2nd picture almost looks like someone put a Vise grip to the barrel! I'd be upset if I put out the cost of one of those but if it's shooting accurately I'd probably have a hard time deciding what to do. Hope you get some satisfaction if/when they get back to you.
Everyone has a different tolerance level for such things. Me personally I probably wouldn’t make a big deal of this as if you slide the barrel in and out it’s going to get marks in the surface anyway. However I agree with you. The pics that jay308 posted in this thread show marks from sliding the barrel in and out. The OP’s pics certainly look more like pressure marks which raises the question if that barrel is indeed factory new 🤷‍♂️
