It's about equivalent, in that the round caliber size is the same (that's a .30 caliber round). The only difference is the casing, which is the part that isn't fired. It has an identical ROF, but the AR had approximately 50 meters less effective range, even though the muzzle velocity of the MA5C is almost 200 m/s higher, somehow. It's a futuristic AK-47 overall, with some slight stat differences.
