This might be a little bit off topic - if so I apologize...
I purchased a Colt LE6920 this weekend and I am trying to decide on
an optical sight. I had the chance to briefly, very briefly, look through
both an ACOG and EoTech. When I looked through the ACOG the
reticle was sharp as a tack but the image was not fully focused.
So far I have been unable to determine if there is any focus setting
on the ACOG or is there is a minimum focus distance. I was inside
a small gun shop so maybe I was too close.
Any help would be appreciated!
