One practical issue to consider regarding scoping is whether it will fit you. It appears there is quite a bit of drop in the stock and I'm guessing the peep sight comes up perfectly. The addition of a scope will reposition the line of sight up at least 5/8" to 3/4". Forgetting that it will negative impact the rifle's value (while costing money) you should consider whether you'll be disappointed with it afterwards. More than likely you'll find you have little or no contact with your cheek. I would strongly recommend you leave it along but just one man's opinion. Good luck...
