not trying to mess with perfection (cause mr. carbon is perfect-what an insane gun) but just wondering if it is possible to change the muzzle (the metal end that is slipped on the end for the band attachment) I have one with a closed muzzle and can't use shark tabs on my shafts-I've had a lot of grooved shafts bend and break at this point. Is it possible to shift over to the open muzzle and even attach the 4 band muzzle to the gun. Just curious-definitely don't want to mess with it too much. thanks, david (i've taken tuna, big GTs, big Grouper, tengirri etc. with this gun-it is so unreal thank you C4!!)
