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.

"Bought this for my jack build. Wheel is hard to turn but if you put %100 silicon oil it lubes up the o-rings so it can move better. Works and feds well with epm-1 stubby mags at 30rps. And good for the price range. Much cheaper than a maxx HopUp. Easy to install aswell. Have yet to have any miss feeds. Would recommend if doing a budget build since price isn’t that steep.

"Good so far, haven't used this in a game yet but when I do I'll update my review if I can.

First impressions, looks good pretty easy to put together, and easy to install. Comes with a RHOP/Flathop arm and a standard arm.

Also comes with 3 O rings, 2 of them attach to the back of the unit where the adjustment nob is and 1 attached to the feed where you insert the magazine. I recommend not putting on the 3rd o ring because it's optional and also causes your mag to unwind and not feed if you're running hi caps (dk about mid caps).

The nub is tight as frick and can not be turned with just your fingers from the dust cover, you'll need to take apart your gun and take it out and twist it with your hand.

Mine also had a bit of wobble (like a millimeter of wobble) but it shouldn't be a problem because the magazine serves as a point of stabilization and you can tabe the wings of the unit if you want.

Feels quality overall and for now I'll rate it 5/5
