I still haven't heard back from them about the Gas/Piston question. I went shooting yesterday, for the first time in months, with the locals from AR15.com. They scouted out a gravel pit down past Olympia (nice 2+ hr. drive for me each way.) that was perfect. One direction had 390yrds for rifle fire and if you wanted to shoot pistols you face the other way in the box and had out to 50 yards. We had some gongs made out of a Helium tank cut in half that now look like cheese graters. A funny thing for me was I couldn't hit jack with my AR15 at 100 yards but I could pound the sh!+ out of the bowling pins at 300 yds. I guess know whites of their eyes for me. And as is typical for us in the gun culture their were 20 of us and about 100 weapons including about 45 rifles. Here is our group photo.
