Although its not the same marker it kind of helps using the reviews from the Dragun forum Barrel Guide
. I like the Scepter kit but instead of inserts you get different backs which I like and the cost is about $50 less. Its basically the same kit. If you dont use many different types of paint you could also get the old Matchstik kit for $100 which comes with 3 bores (backs) and two tips (a 12 and 14 inch).
