I'm a little late to this party and will rain on this Atlas parade.
I have one, and am not happy with it. First of all, the legs spin with the standard feet. When you load it, the two legs roll forward. This happens on dirt and on the bench. I have to dig a quick little trench with my knife in the dirt to keep them set. Can't do that from the bench though.
Second, one of the legs on mine is jacked. It slips past the detent and folds one notch back every now and again. That's no good.
These two things make it worthless to me.
I took a 4 day precision class last year. By the 2nd day, I ditched my brand new Atlas and used an instructor's QD Harris for the remainder of the class. Much more stable. And the 3 USMC and 1 Army sniper who were the instructors all swore by the Harris, for what it's worth.
