So then get that guarder set and find a bore up cylinder set that's unported. They are available individually, possibly by other manufacturers. You'll just have to look around.

Maybe the Guarder cylinder isn't designed with walls as thin as Systema... I don't know. I've never used the Guarder one, so I couldn't say. Where does it say it's 451-550mm?

I've successfully used full unported cylinders in plenty of 590mm guns with no difference in performance. Swapping in bore up cylinder sets also provided no difference.

Granted, all of these builds used tight bore inner barrels, which would require less air volume than a full 6.08mm bore.
