It shoots like none other! I used it on my Shocker and noticed a difference the first three shots! All three hit a tree only a foot wide from 40 yards away! I am impessed! The range will kick the crap out of any other barrel on the market! I can shoot at least thirty feet farther. It's like adding a Flatline barrel to the gun! This barrel allows you to match paint so well that there is no wasted gas so you get better efficency... important if you are a Shocker owner like me. It also allows you to change the bore size in case the weather changes.
It takes a while to find the perfect insert for paint you use the first time... but this is only a minor problem.
I would recommend this barrel to anyone who has a gun worthy of it (not a Spyder, Model 98 or crap like that... no offence). If you wanted, you could even buy different front ends to change the length of the barrel! I like it because you now have to reason to complain if a field only allows you to use their paint. Also, it's fun to terroize people that you can hit, but they may be too far to hit you.
