I'm getting my Grendel AR put together and am looking at my options for optics. I am curious as to who is out there that is rocking a long range rifle with little to no magnification in an optic or irons? My caliber of choice is capable of 1000+, but I will only regularly be stretching it out to a max of 500 yards. Is your setup out of necessity or personal preference? Pump me up with your stories and convince me to stick with something in the 1-4 power range.
