Gents, I have been itching to upgrade from the SIG Kilo 3k's. I've been eyeing the Vectronix Vector IV. I would settle for those, but I've been seeing Vector 21's and a Moskito. I would like to get the Moskito because it gives me long ranging capabilities and night observation. Is the 3x night observation really helpful, or just another bell and whistle that will go unused? I figure, I'd get the Vector 21's and use the extra funds for something else. Thanks Guru's!
