Buddy that is a seriously kind offer, but the Micro ones havent got the kind of weight behind them for what i need to move.
If you imagine this gun barrel (a studio scale Hoth Ion cannon in fact), has to slide back and forth inside a tube, operated by a damper...with no spring (a spring would give too harsh a recoil) smoothly!
Again though, thanks for the offer buddy...i cant believe im being this cheap, but the project is a pricey one
