Pool noodle isn't a bad idea but I'd think it'd lack some suppleness. I'm still going to try it because why not. George: Got you covered. It'll ship tomorrow at noon. Would ship today but, "Sunday". I made my first custom bag design. This one is meant to be used while shooting from the back of a Range Rover in Africa. It'll sit just right on the 3" tubular rails. Last year in Africa I used much heavier bags and they were not optimal. They kept falling and they were so heavy and dense that I lost necessary agility in being able to move the rifle while shooting at game. I didn't bother with adding straps and such yet but it'll get some. This was deliberately a very easy design to build since I haven't sewn other than to attach a button or fix a tear in something like 30 years. Needed to refresh those skills on something easy. Material is cotton/poly 50/50 blend in digital woodland. The local fabric shop did not carry codura. Jerks. Men buy fabric too ya' know. The shape is basically a half-donut in one aspect as you can see in the pic but it's also able to go flat as a 14"x12" rectangle that's 3" thick, or fold up to 6"-7" thick fore end support, flip to the side to get 8-9" tall or flip to the other side for 9-11" tall. The half moon convex side is meant to lay over barricade materials like 4x4 posts and steel pipes like you find on the pickups African game guides seem to all have without having to fiddle with it. In that mode it makes for 3" of pretty firm fore end support. It could work as a toe support as well though it's a little big for that. Weight is less than 4 ounces. I found a "fabric" that's supposed to have ultra high sliding friction so I've ordered a sample and will make a bag out of it and see how that does as well.
