Systema is and always has been a leader in airsoft engineering, and their upgrade parts, like this silent head set, is an excellent upgrade from stock components. The Systema Silent head Set for version 3 gearbox kills two birds with one stone, it reduces air leaks in the cylinder and quiets gearbox noise.

For: Systema Silent Head Set for Version 3 Gearbox
This is a good product and it creates better compression in the cylinder than some other piston heads do. But there is one very big issue with this kit, the holes on the sides of the cylinder head were not big enough to fit into my Echo 1 G36c gearbox. I'm not sure if this is a problem with all version 3 gearboxes or not, but my father and I had to bore out the holes so it could fit into my gearbox, so for the people that aren't as lucky as I am to have a technologically priveledged family, I don't recommend the purchase of this, but for the rest of you, go right ahead, it works great.
