I was surfing around the intertubes recently looking to see if there was any new rifles out there that might qualify as a Colonel Jeff Cooper Scout Rifle and I got to mulling the Springfield SOCOM M1A series of rifles.
Sure enough, Springfield had a rifle labelled as a "Scout Squad" but according to the holy Scout specifications Colonel Cooper delivered from Moses himself (Charleton Heston?), the "Scout Squad" failed the weight (7.7 pounds/3.5 kilos and ideally 6.6 lb/3 kilograms) and length (39 inches/1 meter) requirements at 9 pounds and 40.3 inches. It does however fit the .308 requirement, the ghost ring sights (military aperture sights), and of course it mounts a forward scope (Scout holy of holies).
The SOCOM 16 variant DID fit the length requirement at 37.25 inches and failed the weight at 9.3 pounds! I wondered though how much velocity is sacrificed with that 16-inch barrel to get to that package. Ballistics research indicated 2-inches would result in an approximate loss of 40 feet per second out of a 2,820 fps 150 grain bullet. Not a major concern, in my opinion. 
The SOCOM II variant also fit the length requirement at 37.25 inches but really failed at the weight of 10.5 pounds. It does come with the rails necessary to install anything one could want but that kinda defeats the Scout aspect.

Colonel Cooper thought that a self-loading (semi-automatic) action was inconsequential:
"...If a semi-automatic action were made which was sufficiently compact and otherwise acceptable, it should certainly be considered, but at this time there is no such action available. The whole concept of great rapidity of fire in a rifle has been weighed and found, not exactly wanting, but somewhat inconsequential...The primary purpose of a rifle is a first shot hit, whether the target is game or a human antagonist. Semi-automatic fire does not assure this. As a matter of fact it sometimes detracts from it by letting the shooter believe that if he misses with his first shot he can always make up with a second. This is a bad attitude for a rifleman. As a result of these deliberations all prototype scouts will be bolt action unless and until something new in the way of the semi-automatic action appears." - (Jeff Cooper's "The General Purpose Rifle,"To Ride, Shoot Straight, and Speak the Truth,Gunsite Press, Paulden, AZ, 1988)
Given all of that, I have to say that if one wanted to have a Semi-Auto Scout, I think the SOCOM 16 is a nice fit. It is not a perfect fit (too heavy) but then Colonel Cooper evidently only thought the Steyr Scout only 88% there! Presumably because it was too long and failed to have a stainless barrel.
