I have the atlas on my AICS AX Chassis, so I went with the non-quick release, picatinny rail mount version. Its functional, I like the way the legs extend, the pan, the tilt, the overall fit and finish. Overall the only thing i could say I'd like different would be to switch out the standard rubber round feet with a spike instead, which is an option that I have not purchased yet, but may in the future. So in short, I like it, and it looks great on the rifle. Cheers.
