Matrix Ergonomic M4 Combat Grip for M4/M16 Series Airsoft AEG

"Absolutely fantastic grip. I got it with the intent of replacing the grip of my VFC HK416D (since it's an AR-15-style weapon, and before anybody asks, yes, it DOES fit on 416s and likely the 417 as well). The end result was a very stylish, sleek, and comfortable grip that's well worth the price.

You do have to be warned that on some guns (or at least on 416s/417s), the grip itself attaches to the gun without issues, but the shape of the base plate and the size of the wires and the motor may make the installation rather tricky. It is perfectly doable though, and other compatible guns (again, I only tested this on an HK416) may not have the aforementioned issue. Other than that, it's an outstanding grip and I'm very happy that I got it.

"These are my favorite motor grips by far. I have a few of them and use them on most of my Gate mosfet builds. There is plenty of room to run the wires behind the motor. Looks great and has a nice grab to it. The motor height screw allows a lot of adjustment especially when shimming bevel to pinion, as some motor grips only allow a certain height. Definitely reccomend
