Still not 100% sure the nx8 will replace the elcan specter on this rifle, but it'll definitely have a place in my inventory for good.
My only qualm is the red dot, because of the nature of the reticle at 1x it looks broken up. Not an issue but took me a bit to get used to.
Also, if you're shooting into the sun on 8x, the entire reticle can glare up and flash you. You don't loose clarity of your target but it took me by surprise. Next time I'm out I'll try and grab some photo examples of it.
That is a nice rifle, what make is the lower? The Geissele handguard are quite nice. I also have an Elcan Specter but mine is the OS4X fixed version. Both are top shelf optics. I debated getting an ACOG when I got the NX8 a few weeks back but I plan on building a .308 eventually and thought it would be nice to have an optic I could move back and forth between 5.56 and .308. In my opinion the glass is better on the NX8. It seems with LPVO's the reticle brightness is an issue, almost everyone I have tried and seen have either useless daylight illlumination or it is right on the cusp of being visible (minus a few like the HD Gen II). The 1-8x Accupower did have a reticle that was just barely visible during the day, same with the VCOG. From what I Have noticed and read its more of a problem on First Focal Plane optics, not sure if that is true or not.
