Well, I'll vote for what I use. I have an FN FAL, Stg 58. Built it my self and it is a tack driver. It's not really too heavy. Off the bench with Lake City National Match I could get 1/2" groups at 100 yards with open sights. It has a built in bipod which is handy, but those 1/2" groups open considerably when used.
The FAL is just a classy rifle. I think I'd like the M14/M1A also....I just don't have one.
