Unlike cell phones, digital cameras, laptops, tablets, flatscreens or any other tech related device, a rifle doesn't need to be frequently refreshed. The Mod 2 is about as modern as it gets. Think about each evolution of KAC rifles over the last decade or so. Something very significant had to change in order to justify an updated Modification designation, so I wouldn't hold my breath. Keep training and beating the shit out of the carbines you currently have and upgrade as necessary. Charlie Mike.
