Socoms, in the original configuration of short "hand guard" rail or longer rail that ends at the chamber, can be a challenge to scope. The rifle was not designed for an optic, though it is possible.
I have scoped a SOCOM, both with red dot and with a few magnifying scopes - none were '"scout" scopes, all were standard eye relief.
In my opinion, Aimpoint is the best option, mounted at the hand guard position. With that, you don't have cheek weld issues and you don't significantly change the handling of the rifle.
Another option is an "over action" mount, I tried a few but took a picture of this setup:
DO NOT buy the Millett scope, it was a disappointment.
I also used a Sadlak mount, which worked better but was not fun to install.
Next, you can swap the stock for a chassis-style stock, those usually have a full length rail.
Lastly, you can send your rifle back to Springfield Armory and for about $500, they will install the full length rail, running all the way back to the rear site housing.
And, almost forgot: if you scope the Socom with a magnifying optic, you will probably need some manner of cheek piece, whether duct tape and foam on the stock, or a "after-market" cheek piece, be ready to need one.
After spending about 2 years monkeying with my Socom, trying to get it perfect for me, I sold it and moved to the AR10 platform. I love the M14 action, but it is an iron site gun by design.
Welcome. Always nice to have another Marine around.
