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.

"This unit is literally the same as the regular retro arms unit. They are superb units, and the blue anodized one looks amazing. I bought it because I was in the market for a new hop up unit for my E&L ak 74 and this one happened to be the same color as my retro arms blue anodized aluminum trigger. This hopup requires no modification to fit into an E&L but will not fit a CYMA ak out of the box. I can't speak for LCT ak's. Overall the unit helped me hit 400 fps with less than a 2 fps margin of error in either direction with a G&G green bucking and angel custom 6.01mm inner barrel. As far as ak's go this is the best hopup you can get
