I enjoy my M1A Scout with forward optics. Also own a Mini 30 in 7.62x39. And I have bolt rifles in both calibers. They are great calibers for battle rifles.
As you can tell by my avatar, I have a bit of a weakness for AKs. But that being said, the M1A is a truly beautiful rifle. It's a totally different type of weapon than the AK (which is charmingly crude), that's graceful and beautifully made. Heck, I own both and couldn't be happier!
