If your a walk in hunter I highly recommend the rigem right refuge runner decoy bag. I've been making a few mods to mine that I wanted to share.
First it has a fairly large gear bag on the side. But I wanted it a tad bigger to fit a 5 gallon stool in to it. I had some 500 cordura left over from another project so started sewing away. Now I can carry alot of gear in the 5 gallon bucket stool that will double as a seat.
Second, it has a shotgun pouch on the other side of the bag with a strap to hold and stabilize your gun half way up the bag. The strap is only long enough to clip if the gun is out of the case. I carry my gun in the case and needed the strap to be longer. I had some 1" strap from another project and made quick work of that. (Not the best pic but if you have the bag you get the idea)
If got at least 1 more mod of not 2 more I'm working on so stay tuned.
Oh and they best part is we are within 60 days of teal season
