I'm biased but I'd never regret going with 7.62x51 over 6.8. There are no better 7.62x51 mags in the world than USGI M14 mags and you can get .308/7.62x51 ammo in more places and cheaper than 6.8. Ever see surplus 6.8 battlepacks or ZQ1 ammo at Walmart in 6.8? No, I don't think so.
I just recently traded for a Socom 16 for my son but we haven't had a chance to take it out yet. His SOCOM 16 is from the first year of production of them and has a Winchester oprod which they put the SOCOM 16 labeling on and a Winchester Trigger Housing. The rest is SA except for a USGI fiberglass stock, handguard and sights. Someone put a little work into it - put a National Match front sight, Vortex flash hider, SEI gas system parts, removed the scout rail and put on a USGI fiberglass handguard, and a USGI rear sight. It's shorter and handier than my full size M1A. Would look really nice in a modular chasis.
