I got the optics today, they look great. Now just waiting on the BUIS. One thing is the primary arms red dot will take some getting used to. It requires a person to have both eyes open to focus it well without the magnifier. With the magnifier it is great.
Mike, I shot it the other day and have to say that it sure shoots sweet! Having never shot an AR before I really wasn't sure what to expect. The recoil is not much more than a 22mag. I guess when the wife cools down from all the stuff I have done so far I will have to bring it back to you to put on an adjustable gas block and order a low mass bolt to take the last of it out. The battle comp is GREAT! that sucker doesent go anywhere when the trigger is pulled. This is all very unscientific of course and when I get to put it on sandbags with real sights I think I will be able to describe it better, but for now I am impressed.
And thanks for the tip about having a mag in the firearm. almost always my mags stay full so I know what you are talking about and how that could very easily happen. That one, at the time, was empty though. Its was super easy to check since I haven't made my order for extra mags yet and week or so more that one is my lonely AR mag.
