We have the 7-35mm NightForce on the Mk22.
It’s pretty much overkill unless your using the .300NM or .338NM or LM barrels.
My rule of thumb is basically 1x for every 100m of PID you are wanting to around 1200m in good conditions. So 400m PID from a 4x, 600m from a 6x, 800m from an 8x.
Beyond 1200m you often need more than a strict 1-1 relationship of M/X due to atmospheric conditions.
Also quality of glass and quality of coatings will affect the above — what is also needed to take into consideration is of the Optic will be used with Inline VAS, as certain coatings that can increase contrast during daylight can really degrade light transmission when using at night with clips ons.
For LPVO’s (Low Power Variable Optics) I just keep them at 1x with the reticle on, as generally any quick engagements will be inside 200m, where the 1x is generally preferred, and if you see anything further you have time to dial up.
