It doesn't necessarily need to have been produced by a factory; MACs are simple enough that plenty of them have been manufactured from receiver kits or flat stampings that are bent to the right shape in a vise. If it's a factory-made pistol, it will at least have a manufacturer (either Military Armament Corp./MAC, RPB, or SWD) stamped on the lower receiver. As long as the lower is made to the same specs as the originals, then, yes, a Stony Creek upper will fit it.
