I think the folding stock is useful when storing it it or when riding in a vehicle with it. Hell even putting it a range bag would make it worthwhile, but I totally agree with you on shooting with it folded. Too Hollywood, not practical. I have yet to shoot a Scar 17, and have only heard how nice it absorbs the recoil, and heard reports that it is very accurate. I eagerly await your range report(s).
