Atlas.
I put all my Harris bipods in a drawer after buying an Atlas.
Well, I looked that up, and those Atlas tripods do look impressive! However, they should be at $219 to $279.
Buy them here Maybe you could contact the original poster and sell him one of those Harris bipods that you have laying around for a good price?
Serious suggestion -- a used Harris would do most of us quite well for several decades. That Atlas bipod is a real work of art though!
