Nice gun!
Cool gun mate, but what does the ET do on a single band gun? I don't believe the shaft is whipping with the long, smooth duration of thrust. I know the bubble freeshaft guys don't want their shaft dropping out while a AJ trys to kiss them on the reg, but I believe your a freediver.
Cheers, Don
Don: Maybe he did it unintentionally, but an enclosed track is a way to prevent the shaft to be affected by the whishbone when leaving the gun in a roller gun. If it was an open track there was a high possibility that the whishbone will stop its travel against the shaft butt affecting its flight.
