It is, i think it would be more suited to cqb.I've seen the sig also, but sooooo tiny!
I dont think you can run it with day optics. You would be looking at a pixelated image. Not to mention the reticle is digital.
Im always leary of going fully digital. I like all my optics to be ready to work with or without battery. No red dots for me, give me a FFP etched reticle.
