Future Energy Hong Kong got some CNC'd products that you may want to check out. One item is the CNC Stainless Cylinder Set that will give 300% power-up the M24 airsoft sniper rifle. The other is a CNC aluminium receiver for the Snow Wolf M24. The website is still a mixture of Chinese and English language, which hopefully they get to have a full English language website so as not to confuse overseas customers.
