The first one I bought with adjustable cant and pan could only be secured by tightening a thumb screw which wasn't enough to secure the weight of the heavy barrel and scope and with the narrow spread of the feet($200 shot in the ass)almost caused the rifle to fall off the work bench when it flopped to the side while being unattended for a moment.The Atlas is much more stable with a wider stance and several locking devices(exceptional quality),including the ease of switching to the pointed feet so as to be able to load the bipod correctly when shooting from prone in dirt,grass,etc.
Learned a lot from this guy,lots of great videos.
