I just replaced the Airtube in my .22 storm with the longer version one, I than got Neil to cut the shroud off a couple of inches.
I've always been a fan of guns where the airtube and barrel are the same lenght.
Total length now it's 37"
On BullPups I'm not a fan of the Grip attached to the rear of the stock, I find true Pistol grips much more conducive to carrying the pups in the field, and to be able to get a more straight grip while shooting.
So I cut the extra off the synthetic stock is plenty strong so it can take it.
