I have no military experience, but I'll agree as much as I can with what LRRPF52 says about the A1 config. I have a Colt SP-1 lower that has a surplus A1 upper atop it. (I bought this setup from my brother, who'd owned it for years.) I didn't care a all for the triangular HG so I swapped to the newer A2 type; huge improvement IMO.
But anyway, on to my point. The A1 20" upper makes for about as "handy" and well balanced a rifle as I've ever held. Feels like half the weight of any of my various other uppers, though I know it's only slightly lighter in weight than the next heaviest. There's just something about it. And my brother said it would shoot down to about 1 MOA for him with his 55 gr hand loads, if he squeezed of his shots slowly and carefully.
