The name of the OP was for a Carriar Comp Charging handle.If it were me...I would be studying the Originals here, the orig OEM Benelli, and the Orig CC.A few companies have managed to make something sub standard, there have seemingly only been 2 successful handles made though, those being the OEM and the CC handle.If you can't figure out the CC one, I think you are wasting your timeHas anybody asked Kip if he would supply the details? He's basically out of this market for this product, maybe he won't care. Longshot I know...
