There's a bolt action rifle called the Fix by Q out there that might just be a good modern candidate for the Scout rifle concept. The action and barrel are in a polymer/alloy stock that is fully adjustable and folds.
The whole rifle is very lightweight and is available with a box mag in popular calibers like the 308 and 6.5 CM.
The price is on the hefty side but it seems like it is well designed and thought out. If I was going Scout Rifle I would take a close look at this one. It is 36.6 inches long and 6.4 lbs in weight so it is within the original Scout Rifle parameters as defined by Jeff Cooper.
