There have been several posts here lately that were, at least tangentially, optics related, from the Aimpoints that both my carbines wear, to that ultra-sexy new Mark 6 Leupold on the AR at the Crimson Trace media day, to the big Loopie on the AR in the picture below.
Thus, I should probably take this opportunity to link a good post at Mountain Guerrilla on optics and the fighting rifle. JM knows of what he speaks. He that hath ears, let him hear.
Heck, even Clint Smith has decided that maybe glass on a working gun isn't some newfangled tool of the devil.
Personally, I'm thinking about going either ACOG or to a low-power variable if I... I don't know, find a winning lottery ticket in the gutter or something. It's only the lack of funds and the dearth of >100yd sightlines in my area that keep switching over to magnified glass from being a higher priority.
