Iv got in touch but they won't fit, they go infront of my barrel, and being carbine no joy lol iv recently emailed him with no reply,il have to get onto him once more..as I definitely want him to polish tune and service it. But I also want my barrel and shroud shortened (waiting for an answer off him) plus if he could find cf tube to the exact measurements I want..I could ask him to do the lot, at once..because its going to cost me 50quid for delivery round trip lol , I don't want to spend 50 quid for tune, 50 quid to scr to shorten it, then 50quid for cf shoroud lol that would be 150quid just
