The SOCOM is great, but a little accurizing goes a long way. As stated earlier, get a NM spring guide, piston, and piston housing shims. Installing those will not only improve accuracy, but get you familiar with the rifle.
I also recommend getting a set of Scout sights to put on top, as they allow much better accuracy due to the thinner front blade and rear aperture. The Scout front sight is about the same height, so it will be compatible.
Wood stocks are great. I'm not a fan of the selector cutout, so I get Boyd's. As far as affordable quality though, it is hard to beat a Springfield fiberglass krinkle finish stock, if you can find one.
Also, the Scout rail... its a bit high on the Scout and SOCOM, so I recommend an M14.ca Scout Handguard (SHG). Or just shoot iron sights.
