Ak barrel question

I’ve been looking at purchasing a century draco from a local dealer. I was able to field strip it today and everything seems to be in order. Sights were straight, the numbers matched, and had a 1968 marked trunnion. The only things that’s bothering me is that the rifling didn’t seem very sharp. To make sure I wasn’t imagining things I went and checked some other ak rifles at another shop and the rifling on them seemed to be defined much better. Is there a chance the barrel of this draco might be getting close to worn out or does it sound fine? I’d just hate to spend $400 on what’s basically a toy only to have a bad barrel.

It could be shot out, thats not unheard of.
