While it's true that Mike Bush designed the repeater conversion for the 40X/XB and the V22 repeater action, to the best of my knowledge, Vudoo Gun Works never offered a repeater conversion for the Remington actions. Mike put the CAD/CAM drawings out there for the conversion to several gunsmiths, but - again, to the best of my knowledge - Jonathan Elrod was pretty much the one guy who specialized in doing the conversions while Mike & VGW were working to bring the V22 action to market. I've always thought that one of the main reasons Mike designed the conversion was to get as many of his V22 magazines out there & into the hands of a good number of shooters to 'proof' them and provide him with a lot of feedback whilst he was working on the V22 action. And no doubt, when guys got their relatively inexpensive CMP 40X/XB actions converted and were able to reap the advantages of having a .22RF repeater that was nearly identical in weight & proportions to their M700 CF rifles, it was a game changer, whether they wanted an accurate RF trainer for their CF comp rifles, or for all the .22RF competition games like NRL22 & 22RF PRS that were just becoming popular. I've always thought that his marketing strategy was genius - making the repeater conversion available to take advantage of the thousands of CMP 40X/XB rifles out there, and at the same time, creating enough demand for the V22 action so that when they were released, the demand was already there.
