Here's the first review of the Hephaestus Custom Project T done by Bunny Workshop's ThisIan. This is a limited edition Gas Blowback TAR 21 Rifle which uses the GHK gas blowback system with lots of CNC'd parts. On Green Gas and 0.20g BBs, this has an initial muzzle velocity of around 340-360fps. Available in Black and Olive Drab, price is US$620.00 and in stock right now at Bunny Workshop.
