Anyone have one of these? Wondering what to expect. Got one on the way. Reviews are all great but you never know. Also, getting ready to do a Geissele trigger. Which one should I get? Don't even know where to begin. I use the AR with iron sights and under 250 yards. The 22 conversion upper will small game hunt and target to 100 max, going to scope or red dot that upper but haven't made up my mind yet.
