Any updates on the 3.0? Currently using the outdoorsman system and may try one of these I'll have to measure my Leica though because they don't seem to have an offering.
I have to brag about IA customer service. I put a 40lb bag of pellets in there and and sent a picture in to Joe to get help with fitment. He was quick to respond and gave me a couple options to try. (I ended up lowering the shoulder straps on frame about 1/2")
I need to try with a bit more...
