I really like the way Tippmann has set up the mechanicals in the X7 Phenom and the Crossover. I like being able to run without a battery and have a reliable spool drive moving paint in a relatively efficient marker.
My biggest complaint with both of these markers is the stock barrel that they come with. The X7 stock barrel is easily the least accurate barrel I've ever used. It's a good thing the market is filled with third party barrels.
So I purchased some SLY barrel backs and their double carbon fiber barrels at a really good price. I've been using one of the series with the autococker backs and very happy with the barrel.
Unfortunately, the unique design of the X7 and Crossover bolts are causing jams when used with smaller bored barrel backs. I made the following two videos to show the issue and what I've done to address it.

Note my surprise at the end of the video when it worked on the X7. I'd recommend taking 1/4" off the back rather than 1/8" to avoid the jams.

What surprises me the most is that I couldn't find anyone else talking about this. It could be that my Google-Fu is failing me or maybe there is government hush money involved. I know that the Crossover hasn't been welcomed as much as expected (I blame the Gog Emney for being a solid mechanical at less than half the price) but I still would have thought there would be some chatter about aftermarket barrels causing jams on these markers.
If I'm missing something, I'd love some feedback.
