About EMG

The EMG vision is to manufacture products the world has never seen before; products we would put our name on, and products that hit the spot! "EMG" (Evike Manufacturing Group) was spawned from the realization that if you want something done exactly the way you want it, you need to do it yourself, and we did just that.
We took our 16 years of knowledge as the market's lead retailer, our network of 300+ superior manufacturers, to work with inspiring top innovators in the firearms industry. That combined with the vision to invest into the Airsoft industry, an industry we believe in, EMG was born.
