So I'm in the process of getting my setup down, as I'm going to try to make a couple F class events this year. I've always shot off a harris 9-13 but will be buying a proper ski-pod, haven't made up my mind on which one quite yet. I've shot enough prone to know that I'm going to want a fairly tall setup which will have the bipod near 10", looks like there are a few on the market that go this high. What I don't see anywhere though are rear bags that will work. It seems like the standard is about 2.5" and a tall one is about 4" I'm thinking I need a 5.5 to 6" tall rear bag but where to get one? Anyone make custom bags? I know I cant be the only one looking for this as it seems much easier to stay in position if your skull isn't dragging on the ground...
