cmryan... I highly recommend thomasjohnmurphy's upgraded airsoft units. I bought one, and have finally installed it as well as the barrel extension, metal tracks, laser pointer, and RX14 board. The Tiger is looking awesome. I fired off a round and didn't even see it! It bounced around the living room and I have no idea where it went. I stood up a heavy plastic shoping bag [not the thin ones from the grocery] and it shot right through the bag at about 12 feet! I have no idea how many fps this thing has but it is impressive. This tank has been disassembled for a couple months and I was so glad to get it running I took it outside for a spin. Unfortunately, while checking out it's climbing ability with the metal tracks, and turning around to go back down the hill, I snapped the barrel off in front of the barrel extension [] and at the end of the inner barrel... I even turned the gun to the side, but because it was dark I couldn't see that well and soon found out that I didn't turn it far enough.

Anyway, TJM - thank you! More than a fair price for your efforts, and now I have an airsoft that is tank worthy. I've shot myself with the stock HL and an HL that was upgraded with a VS Tank spring, but will not be testing this gun out on myself - or my wife while she is walking away from me!
