I just picked up a DPMS AR yesterday for my wife(at a non-inflated price from a great member on here) and am wondering what I should do as far as a scope. I kind of want to move my Vortex Strikefire red dot from mine and put it on my wife's and get a nice long range scope for mine. The reason is the DPMS is nice and light so I figured it would be good with the red dot for clearing the house or close quarters. Mine is a RRA Operator that is a heavy pig so I figured a long range scope would be good on her. I don't want to spend a ton on one right now, maybe below 200 if possible. What are your thoughts on my options and am I correct with my thinking on putting the long range scope on the RRA?
