Ice, this is the same weapon I had at LC4. I was just too lazy to cut the barrel down before the game. The barrel is a metal two piece Hurricane thing. I only used the back end part and attached a Guarder M933 front metal piece to make it short.
Its shooting about 350FPS w/.2g bbs but it should be closer to about 370-380 with the upgrades I put in to it. Just before LC4 it was chrono'n an avg of 370FPS.
Its got a PDI 150% spring, Systema full cylinder, silent piston head set, and a Systema tight bore BS barrel. It was originally 14.5" but I cut the inner to match the 11" barrel profile. As far as range and accuracy, its about the same as it was before I cut the barrel down. I'm hitting the same targets in my backyard as I was before.
