I recently got a Bear Kodiak Magnum and I figured a strap on or slide on quiver would be cheap, but no sir!
The cheapest decent one I could find was 50$, with the one I would want running 65$ or so. This seems like a lot of cash for holding arrows. I got a quiver for my old bow that used a universal clip so I switched it to my Samick Sage, but I'm not drilling holes in my Kodiak Magnum.
It seems like it would be a simple thing to make, the only thing I would want to buy would be the rubber piece that grips the shafts.
