If you are willing to spend the money, LRB makes an "M14" variant with a scope rail built into the receiver. Fulton Armory also will build you a semiauto M14.
I have a Springfield Armory Scout rifle. It took a fair amount of tweaking and selective parts replacement, but I was able to get it to shoot consistently under 1 MOA at 100 yards with handloads. I replaced the stock forward mount with an Ultimak front rail and mounted a Leupold FX-II IER 2.5x Scout scope on it. I have lower 1/3 co-witness on the iron sights through the scope. It's a very handy setup.
The Scout along with the LRB Tanker are my favorite M1As. Also look the coolest.
