The late Col. Jeff Cooper is who put this thought into my head. In The Gargantuan Gunsite Gossip book, Col. Cooper has several very positive references to lever guns being extremely good all-round carbines, close to his favored bolt-action .308 scout. Not sure I would do this, but am looking for information (thinking a 35 Rem with a scout scope and a ching sling might be a sweet setup). Here is an example of what he says from p. 628 of my 2001 reprinted edition:
"The installation of a CW ("Ching") Sling on the M94 30-30 is a somewhat complex proposition, since there are no satisfactory places to install a sling socket forward of the butt-stock. One answer is to fit your Cobra sling with snap-hooks. Then a ring socket can be installed in the toe of the butt and another attached to the magazine just forward of the fore-end, using an Uncle Mike base. For the center-mountingthe saddle ring, which comes standard on some M94's, will suffice very well (for a right-handed shooter). If your piece does not have a saddle-ring you can easily install one."
Having never seen one of these saddle ring kits I wanted to know how firmly they were affixed into the gun. Sounds like that's a non-issue, they are more than a decorative doo-dad per your answers, thank you. Since you are still reading, here is another question: for the rear ching sling-attach point, could a butt cover adaptation be used to hold the rear ring socket, instead of attaching the ring socket directly into the butt-stock toe?
