I have an Aimpoint and an EOTech that I might occasionally switch out on the same weapon. Aimpoint has an ARMS throw-lever, and the EOTech is stock right now, but I'm hoping to get a GG&G Accucam lever for it. When you mount such optics, and it's settled in a slot on the rail, do you push it that extra few millimeteres forward, or do you push it backwards before tightening? I assume recoil would cause it to slide backwards if anything, so would sliding it all the way back maintain a better zero? Pretty reliable switching optics as long as you put it back in the exact same spot each time using the questionable method above? |

+1, push it all the way forward. Accessories mounted on the rifle have mass of their own, in recoil, they will be jolted back with the rifle, if there's a slack ahead of the mount and rail, the mount will take it and continue the backward motion until it stops against the recoil lug in front. Think of a car that's rapidly decelerating, the driver is still moving forward while the car stops, he doesn't slow down at the same rate as the vehicle, hence the need for a seat belt to stop him from continuing to travel forward. Or something like it
