No, the MEC SF has the HK53, an ultra short "Assault Carbine" (under H&K nomenclature its actually an SMG) in 5.56x45mm based off the HK33 assault rifle.
There are two well known G3 "carbines". The G3KA4 formerly manufactured by H&K and the MC51, designed by Bill Fleming for British Special Forces. It is currently Manufactured by Imperial Defence Services, of the United Kingdom.
I dont know about the service of the G3KA4 to any great degree, but the MC51 was used for a very short period of time due to reliability and controlability issues. They were rapidly replaced by the HK53.
They are however, a rare, interesting weapon in that it is the only 7.62x51mm SMG (its barely larger than the MP5) that has been produced in any numbers. The new manufacturers claim to have solved the recoil and reliablity problems, however.
