Future Energy Hong Kong just released some upgrade parts for the Vega Force Company MP5 Gas Blowback Airsoft Submachine Gun. If you have already have one of the VFC MP5 GBBs, then you can upgrade the bolt with their bolt inside copper cylinder or replace the hop-up with their CNC'd aluminiun hop-up set.

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.
