Reverse threading can cause problems if not done correctly
Review:
I have used this barrel for about a year now, and I must say I am very impressed with it. I met the company at World Cup this year and found out that they also made the Barrels of OTP and the also make barrels for several other companies out there.
This barrel is a very high quality barrel, there craftsmanship really shows through in this barrel. It is by far better then the freak, or any other kit I have used to this date, see above, I have not used all the barrels out there but of the ones I have this one is the best. This barrel shoots darts, is super quite, and I have not had a problem with it cleaning on the rear chance of a break, it only takes me about 10 shots to shoot clean. The only minor problem I have found with this barrel is the reverse threading of the inserts. The problem occurred when you go to screw the barrel into the marker and the insert is not tight enough into the barrel it will start to unscrew itself. This is easily fixed with the tool the have supplied with the kit and just by tighten the insert down before you start to screw the barrel on. Really not a problem if you install it correctly.
Conclusion:
Over all this is a great barrel you will not be disappointed with it. If you want one of if not the best barrel out there get this one!
