There are so many variables that point against high accuracy in these guns that it's unusual for one to get under 2 MOA consistently.
There's the loose chamber needed for fast cycling, the usually loose front stock work, the sometimes inconsistent lockup, the battering that ammo gets when it slams in...The list can go on.
Then there are (let's be frank) differences in bench setup and shooting technique - not to mention the poor to awful trigger in the gun.
I've seen a very few that will shoot MUCH better than that, but about 2 MOA is what I'd personally expect - and settle for.
