The ideal optics mounting height often isn’t a clear decision. One rifle might need its optic low to the rail, one might need it high. If you’re co-witnessing with iron sights, do you prefer an absolute co-witness or do you want the irons in the bottom 1/3 or 1/4 of the optic’s window? Now, thanks to Elevated Technologies’ “The Slide,” one mount serves all height options and quickly and easily transitions from low to high and everywhere in-between.
Loosen a single bolt and the top half of the mount slides up and down on the bottom half. Fit is snug enough between rails and grooves to ensure fastidious alignment but loose enough to ensure easy sliding.
Top halves are available for many different optics (MRO and Aimpoint now, more coming soon), meaning if you change optics you could simply replace the top half instead of having to buy an entire new mount.
TTAG is beginning the review process on one now.
