inserts allow you to use almost any, my favorite are pmi premiums with .689 insert.
Accurate,interchangable bore sizes,don't need to buy new backs for different paint sizes
i bought the 14inch freak kit from my local store for about $150. i was going to get the linear but saved some extra money and got the freak for the interchangable inserts. They are very useful if you shoot different kinds of paint. This barrrel is much more accurate than many stock barrels. If you have a few extra bucks i reccomend getting this barrel. In a test shooting at a target 50ft. away using pmi premiums with the .689 insert. There was about a 5inch grouping with many paintballs on top of each other for 25shots. I also went to the field nearby and played and hit a player at about 70ft. away with one shot. This was probably luck, but the barrel helped.
this barrel is very accurate and can change bore sizes in a few minutes. Even though it is kind of pricy if you have the money you should get it. I haven't had any problems with this product so it is getting a 10.
