What do you want the bipod for? They all have pluses and minuses depending on intended use. What I would use at the range with a heavy .338 Lapua is very very different than what I would use my with my ultra lite 6.5 Creedmoor on a sheep hunt. Do you want it attached to the rifle all the time? Does it ever need to come off? Do you want it attached when hunting or want to be able to throw it on fast or slow? Lots of great options, Atlas for the range, but then which Atlas? Big differences between them all, Super lite, maybe a Spartan or a Rugged Ridge. How important is price?
If I'm at the range and weight does not matter then a BT-72 is as good as someone needs, no need to spend 1K. If weight matters, it's all the Spartan. A Rugged Ridge is right in the middle. If price matters, buy a cheap Harris Knock off, will work just fine on a hunt.
