The ARES KAC Stoner LMG replica has no trademarks.  In fact, there are no visible markings of any kind on the full metal receivers.  Some of the component designs, such as the hop-up unit, are surprisingly similar to the ones found in Tag Art's KAC Stoner LMG conversion kit.  The LMG comes with a 500-round box magazine, which also houses the battery pack.
