K I have a S&B PM II 4-16x50 MKII. Sighted it in, ran a weapon through some drop tests (Not my gun, doing an eval for a client prior to production), tried to re-confirm zero after drop test (nothing serious, knocked it over from the bipod, normal private type stuff). So when I try to re-confirm zero rights keep moving right regardless of windage movments. If I don't touch it, then they group, but regardless of adjustments rounds move right. Looking through the scope everything looks fine, look through it backwards and there looks like a "crack" from the 3 o'clock down to the 6 o'clock. Paralax adjustment? or did I really just destroy a demo by tiping over a rifle off its bipod?
