Roger that smokiniron. I bought a 5 round Bushmaster mag for the range. I love it's construction quality and it encourages me to get up away from the bench after every group. A scope may increase fire rate at the range as it's easier to get on target.
With irons my shots at 100 yards at the range take forever, as I'm never truly happy with my sight picture. I currently have a scope on it and I have to say it is very pleasing to get into ~one-inch groups. I have the A2 handle in my shooting bag. The A2 handle sight never appears to go out of zero when I remove/replace it.
