Got a mono Comanche and I was wanting to adjust the rear sight but even with the screw all the way out and a heat gun I cannot move it . Now my plan is too take it all the way out and if needed sand it so next time it will move if I need to adjust it . So does it go out both ways or only one side ? If it's left to right or right to left is it with the gun facing away from u or towards you ? Please help thanks
