I added a rest to my Gorilla Kong XL lock-on that I use for gun season. More for concealment rather than a rest. I don't have any other pics than these, but after I took these I purchased some camo fabric and attached heavy duty velcro to it and if it weren't for my blaze hat...you'd barely see me in the tree.
I agree with "Brocster"...
However, where I am in WI, most of my shots are 80-120 yards. I feel that if I can't hit a target with a scoped rifle at that distance, I should put the gun away. My sentiments, too.
