You have some choices.
1. Handguards can be glued or look for a replacement on ebay as they do show up.
2. If you are buying to rifle for shooting the bore may contribute to the rifle being less accurate but if you aren't shooting it for accuracy it looks like fairly clean barrel.  I had an M1 Garand with a barrel over 4 ME (don't know ME) and it was all over the place at 100yards.

In summary, it depends on what you want and how you are going to use the rifle.  My opinion.

Good Luck
