I don't know that either match your exact needs, but that was a quick look.

why not just use a sling?

yes they do make them but an easier and most likely cheaper method would be a shoulder strap for it, that way it would not have the shance of getting caught in any gear when you might need it, the other option is a scabbard made for tying onto the botton of a hiking pack. those can present a problem in the fact that you almost have to take the pack off to get the rifle out, especially if you have shorter arms

You could have one made by a Leather Craftsman..

Check out Cabelas . . . they offer a number of packs specifically designed to carry a rifle or bow where it is readily accessible . . .

I know exactly what you mean and have an idea why you want it. It is basically a saddle scabbard mounted on your back so you can grasp the stock and draw the carbine over your right shoulder, with your right hand and bring it down to firing position rapidly. Right? I too want one for my Rossi M-92 SRC! It would leave both hands free for hiking, climbing, or fishing. It would protect the gun from scratches and dings, and if waterproof, would keep it dry when waist-deep in a salmon stream. And keep the rifle handy if a bear wants my catch. Unfortunately, I do not know of anyone who makes such a back scabbard. I guess I will eventually have to make one myself. Doc
