I know this has been discussed before and maybe i didnt get the answer out of it that i needed but i think ill just ask right out. Im from canada so i dont want to order my dw barrel from the states and pay more for shipping and all that good stuff. it says on the website that " I MUST USE SMART PARTS FREAK INSERTS" with the barrel, now i looked it up and im seeing all these gog freak inserts and all these different kinds of inserts from different companies. I know smart parts isnt around as a company anymore but im just confused on what inserts i can use. If i buy the fibur barrel can i buy the gog freak insert kit and its the same thing? if i order it online from the states it only comes with the 4 inserts and the barrel but if i buy the gog freak kit or whatever freak kit it is i can get 8 inserts. So pretty much what i want to know is if i buy a fibur barrel what kit can i buy for it that will work? As long as it says freak on it itll work? Thanks guys.
