So after upgrading to an IBU2 pro and 6 channel radio, and being frustrated with the stock HL elevation setup I pulled the turret apart. so I knew I was never going to use the airsoft again so I pulled it apart and gutted it, also trimmed it down to make sure it was not hitting anything under it. well once I pulled the spring loaded bar out, the barrel moved just under 3/4 of an inch stop to stop. well I had a few micro servos from some old helicopters and thought hummm.. so I hooked it up to the IBU and with the horn that was on it I had about 5/8 of an inch of throw SWEET!!! also gave it a little more negative elevation while I was at it.
