ZCI Polymer Motor Grip for M4 / M16 Series AEG Airsoft Rifles

"-Very comfortable
-Easy to install
(Had to sand down the posts on the inside a bit to fit my E&C gearbox)

-Brass threads in grip
-Cheap price

"A fabulous alternative to the standard a2 grip also made by zci. I put this one on my custom m4. It has brass threads in the grip and air holes in the heat sink. I put these zci grips on any m4 i encounter and never had issues. Some other brands have had the brass inserts come out when tightening the heatsink so these zci ones are superior 5/5

"Updated Review:

One of the screw holes for the motor heat sink seemed to have failed qc or something and was really tight, ended up stripping a screw.

Was able to extract and replace it with a torx head screw to avoid further stripping

Heatsink screws are M3, 8mm, 0.5 pitch.
