The 10x42 Mil Quad Worked Fine for me in low light,I killed a doe on opening day 15 minutes after sundown in a cut over ricefield 250 yards. Next week I went back and Killed a 9 point 5 minutes after sundown in the same field at 125 yards. No problem seeing the reticle at all. Now I expect that in deep woods the reticle would not be that visible at sundown but in the fields where I hunt mostly the reticle works great. Seeing how the 6x42 is going to be brighter than the 10x42 I would expect no issues seeing and using the Mil Quad reticle at any legal shooting time.
