I think performance bonus is Def a plus the more ammo you can get the better esp with the low amount of ammo with that weapon. As far as scopes whatever scope you feel comfortable with some love ambush and others shortgaze I even run tacsys which I'm sure I spelled wrong if the board calls for it. If I remember hand laid stock effects range but if your running shortgaze that shouldn't matter to much on smaller maos. What's the other perk you got that you didn't mention?
