I have owned a freak kit, now I own a un1tec kit. I would never again choose a freak kit over the un1tec. It's much more expensive, heavier, easier to damage (anyone stepped on their bore insert yet?), it's a 2-piece which results in worse results as opposed to the one piece construction of the un1 barrel and to top it off, changing threads is a bitch as buying a new freak back costs more than a single un1tec bore with threading sleeve.If you dont have a lot to spend then i would go for the lucky barrel kit.
If you have a lot to spend then go for the freak
