My thoughts are the M134 would likely be less accurate as you've got more mass moving about in it that a M240/MAG 58.
If however both were bolted down to something immovable, and you're taking recoil and movement out of the equation (and ignoring wind, humidity, etc), the weapon with the longer barrel is likely to be more accurate.
Weapon wear and tear is also likely to effect accuracy and as the M134 hasn't actually been produced in many years and is therefore likely to be much older....
