I love my Gecko II. I know Kevan, the guy who created the bag and started the company, great dude. The bag is a little large if you use it as a rear bag with a PRS style stock and a short bipod, but it's great on pretty much everything else. They ship it absolutely stuffed with fill (on purpose), so if you get one do yourself a favor and take some out, tune it how you like it, put the extra in a ziploc, and set it aside.
