I know this has been sitting dormant for a while, but do you know if any of the users that bought the A5 threaded barrels have used them successfully with the Crossover? I'm trying to see if I can find something that will work consistently in the Crossover without getting jammed or tearing up the bolt/barrel. So far I know a Tiller failed spectacularly, and Tippmann's own Crossover AC adapter even has started to show bolt wear on the back edge.
I think Lumberjack was onto the issue with his comment at the top of page 3, but I wasn't sure if you'd done anything in design to account for the bolt grab and/or if you'd heard good success stories from A5 buyers?
