I love the M14 platform. I have owned three, and there is likely a SOCOM in my future - so please understand that what I'm about to say is by no means an attack on your rifle.
An M1A (and probably a SOCOM) can
be a bit of a challenge to scope effectively. There are a few reasons for this:
#1. If you don't have the model with the rail that extends all the way over the action, you will need a scope mount. Most mounts for the M14/M!A family of rifles are less than great - and even the good ones need to be carefully installed - preferably by someone that knows M14's. You don't need a gunsmith...just someone that knows this rifle's quirks.
#2. The recoil impulse on an M14 is....different. The main recoil (rearwards) is nothing to worry about - after all, it's a heavy .308 gas gun. What is a challenge for some scope to tolerate is the forward impulse that is generated when the op rod and bolt run forward and come to a sudden stop. That results in a short, sharp forward shock.
#3. M14 scope mounts tend to generate a "chin weld" instead of a "cheek weld" due to the geometry involved.
For these three reasons, when I purchase my next rifle from the M14 family, it will be a 16" barrel, an I will put a long eye relief optic into a scout mount. My personal choice is an aimpoint that has a 2X magnifier (I know, strange and unusual animal....but it works) This also dovetails well with my intended purpose...which is shopping for bacon during the hours of darkness.
