What chamber are you running? I've found the 5.56 match chamber works well. This chamber has the NATO freebore with the leade (sp?) cut for the ogive of the heavier Sierra Matchkings. The extra freebore lets you seat the 80's out to take advantage of the limited case capacity.
I've been getting away with a flattop receiver. I use an "F" height front sight, and so far, haven't run out of elevation at 600. Maybe I've just been lucky. LOL
I really like the AR platform. IMO, it's not as much fun as the M1A, but they're not tempermental like the M1A's either. I've found the AR's to outshoot the old rifles any time.

This rifle has a White Oak float tube and is running a .223 match chamber. It seems to be o.k. with loads up to 77gr so far. I haven't tried any 80 gr loads.
Next barrel will probably be a Krieger with .223 Wylde chamber and 1:7.7 twist.
The first service rifle match I ever shot was with an M1A. The AR seems so much easier to handle on the firing line though that it almost feels like cheating.
