Hey all,

I just recently bought a WE M4 AEG, and changed the stock pistol grip to a Magpul MOE grip. The motor just barely fit in, requiring the adjustment screw to be fully unscrewed in order for it to fire. The base plate was the only thing holding the motor down. It fired fine in auto and semi, but with a higher pitch normally associated with the motor height being too high.

I then decided maybe I could lower it by checking if there was a wire pinched or something. I put it back together and then it made grinding sounds no matter how far the motor was adjusted. It would either not work at all when the motor was too high, or when it was lowered it would just grind or barely cycle. After playing with the motor adjustment screw and shifting the wires back around, I had no luck.

I then installed the stock grip back on it, but the exact same problem happened. Before I changed the grip it worked perfectly fine, but now with the stock grip on it I am getting the same problem. I don't know much about working on AEG's, and I'm probably gonna bring it to a gun doc, but I thought I'd ask here for help before I go do that.

Thanks guys!
