Product Information:
I got this set to improve the air seal on my gun when I installed a longer inner barrel. This is a great set especially for the price, it dropped right into my gearbox, replacing my stock parts. The only problem I had with it is that the air nozzle didn't have perfect air seal, but I put a modify air nozzle on and the air seal is way better.

Very cheap
Fit perfectly in my gearbox
Great air seal

Air nozzle wasn't great but it was easy to replace
Does this fit any m4/CM16
