I hope they improved since the model 2000 magnium .177 , barrel droop about 25mm and impossible to fit a scope to that will work, works will factoery sights due to the way fitted ,why Gamo bothered to put the grooves for a scope is beyond me ,as no mounts availabe will compensate for this amount of droop
