The Acog 4x and acog 6x arent working properly on the crossbow on experimental, since the minimun zeroing of 100m is fixed, so you cant shoot any target in less than that with the scope, making it really hard to hit targets under 80m with one off both scopes. I suggest that a 75m, 50m and 25m zeroing parameters are added to the scopes, so they become more usefull
