RETRO ARMS cylinder head, C Long has a special shape
The nozzle pipe length is very long at 36mm.
The body is machined from EN AW7075 and the cushioning is made from polyurethane. 
The cushioning material is 1mm thicker than the stock, and a gentle taper is created from the piston striking surface to the nozzle pipe.
This allows the compressed air to flow smoothly.
This reduces pressure loss, and simply replacing the cylinder head can improve initial velocity slightly.
Because the cushioning material is thick, the piston is set back 1mm compared to the stock.
When installing, please check for interference between the piston rack gear and sector gear.
