Well, this barrel kit is simply amazing. It is nice being able to purchase whatever kind of paintball you want and know that it will fit in a barrel no matter what.
When I used this barrel, I never ran into a single problem. I never had a problem with finding the correct size or anything. I always tested between 5 and 10 paintballs to ensure that the barrel insert I chose was the right size. Once I was sure, I was playing all day, no barrel breaks nothing.
As a matter of fact, in the 2 years I used this barrel kit, I never had a barrel break. That is no lie.
The inserts easily slide in and out of the barrel back. Once the barrel back is screwed onto the marker, the insert isn't going anywhere. You can be insured that the insert won't move around or spin during hard play.
There are 2 types of freak barrel systems, stainless steel, and aluminum.
The aluminum ones are lighter, but less durable as far as denting and what not. The stainless steel ones are a little bit heavier, but are almost indestructible. Not to mention that some of the sizes are the same.
If you are looking for a great barrel kit, the freak is the one for you. It has a great price tag, and is very easy to use.
