As some of our most reliable and dependable weapon systems reach the end of thier life cycle, other weapon systems have arrived offering unique, different, and specialized capabilities that build upon and improve what their predecessors did. There are the X36 and S552 series they offer very familiar features however provide a different tactical edge with Rail Integrated System carry handles, compact side-folding stocks, and ambidextrous fire controls. You'll find other designs such as bullup weapons like the AUG or L85 that put the magazine far behind the trigger providing shooters a longer barrel length while remaining as compact as many other guns. Or if you prefer something bigger there are the T3 series of guns and grenade launchers to satisfy those cravings.
