Trying to mount a new 6-18 x 50 scope on a new 224 Valkyrie upper with new 2-piece Nikon P-series AR rings. Have used the P-series before on other ARs and like them. But today, needed substantial shimming of the caudal ring to zero scope with a laser bore sighter (indoors, 8 yds), and scope turret is at maximum elevation. Yes, I know the 8 yds isn’t ideal, but before when I’ve done that, at the range when I zero later, it is still sighted low, not high. Switched to another spare scope and same issue, so I’m suspecting the mounts? I switched them around with the same result. Should I be using a 20MOA anyway, given that it’s on a 224 Valk? Frustrating.
