The NcSTAR Ultimate Sighting System Gen3 3-9x40 Rifle Scope has a reticle that is caliber for use with 5.56. However, it could be used with a 6.5 Grendel but the reticle holdovers will not be accurate. The Red Dot does not come in tan.
No, it will not as you do not add optics of this type to handguards which is what the MLOK split rail is, and what you would put lights and laser pointers on
The red dot is not wired.
Yes, this has up to 9x magnification. So an object at 100yds would appear 9x closer.
Yes you can change the color of the reflex dot.
One is MilDot style the other is MilRad style, pics 9 and 10 show them.
Unfortunately, NcSTAR does not specify the "footprint" of the red dot.
