Low Light/Night Training with an AR9

Getting the feel for using a light for night shooting. Adjusting optics to not wash out in the light, seeing how settings change and overcoming the transition from light to no-light target acquisition. Basically just figuring out what this setup does and what to look out for in a night shooting scenario.
Setup is a custom mix of Guntec AR9 parts and various other parts from companies I trust, being fed my a MEAN Arms Endomag.
