I've owned a couple different Harris bipods, including the 6-9 recommended in this thread. I purchased an Atlas recently and I must say, it was worth EVERY penny. If I could do it all over again, I would have just bought the Atlas and been done with it. Get the one with the QD mount and don't look back. Yes, it's extra coin, but if you plan on staying with this sport, there's a good chance you'll end up buying an Atlas down the road anyways. Sure, some guys prefer the Harris, but for me and many others the Atlas is the way to go. The ability to load the bipod is a huge advantage in keeping your position consistent through recoil, especially for a novice shooter like myself.
