Just curious about the requirement for 1-4x variable.....not being a 3 gun shooter, what in a 3 gun rifle stage would need a 1x equipped AR? I ask this only because I run a 3.5x ACOG on my AR-15. My normal training drills include aimed shots ranging from 7 yds to 200 yds....shooting against the timer. I've never considered fixed power optic I use to be at a disadvantage within that range. I can shoot both eyes open with the ACOG....about half the time I forget to do so.
