I bought this scout scope for a standard Mosin-Nagant 91/30, replacing the rear leaf sight with this scope on a custom made mount designed specifically for this rifle. It works incredibly well, especially if you want to scope your Mosin but can't or don't want to go through the trouble of mounting a regular scope. After close to 300 rounds, it hasn't moved a bit. I have hit steel targets at 430 yards, and will soon be trying my luck at 600.
Pros: works well, extreme value for the money, great for Mosin-Nagants
Cons: none
