They can though. But it used to be fairly well proven that the AR10 versions were pickier than the 15 versions. That may well all be worked out by now, as the early ones came in 308 thats a fairly accurate round to start with. Not like these groups are all becuase of the creedmoore.
I might take a run with the AR-10 carbine (as much as one can call a 10 lb rifle a carbine) which has a Rainier/Shilen Ultramatch barrel. I saw some headway on it the last time it was out prior to the Hog Hunt, so we'll see what it might do with some Matchkings. Realistically, though I think it's a 1.5"-2" rifle
There is also a bull barreled Armalite 15T here here that shot very well in the past, so I might just slap a scope on it and let fly.
