Bit of an update, I went ahead and did it, hardly had to file anything away to fit the longer barrel through. I'm using 2 10mm o rings to support the front of the barrel within the outer barrel. The 220mm Crazy Jet barrel is a perfect fit, ending just inside the CCW thread.
With the space I have I can't comment on any increased range or accuracy, but certainly the accuracy is still as dead on as stock. I have added a Maple Leaf deception 50 bucking with the Maple Leaf nub, when I next go skirmishing I will be able to dial in the hop and see what it can do, as well as chrono.
