PSG1 fluted barrel at X-Fire

Not long ago X-Fire added a new fluted outer barrel designed for the Marui PSG1 to their pages. The new barrel retails at around 8,000Yen and will add a farily distinctive look to your rifle. There are five flutes to the barrel with the wall thickness varying from 2.3mm to 3.8mm, and all finished in a black anodized finish. My understanding is that you use your original barrel spacers and end cap when you fit the new barrel.
