Ok, I need some advice... I've settled on 2 options for optics on my SIG556... I either want to get a Nightforce NXS 1-4x24 mildot reticle, zero stop & 1/4 MOA turrets. This option will be "adequate" at CQB and mid range both...OR I want to get a Nightforce NXS 3.5-15x50 mildot reticle, zero stop & 1/4 MOA turrets but add a trijicon red dot system at 1 o'clock further down the rifle... Creating 2 specialized systems to be more versatile... I will be doing mostly range shooting out to 300 yards, but want the ability with this setup to be used as a survival weapon (should cataclysmic events necessitate such a thing)... This will eventually be my wife's primary rifle after I finish an AR-10 build....
