If you are tired of the at flimsy multi-piece outer barrel that comes with your Echo 1, JG, and Tokyo Marui M4/M16? Then the JBU One piece M16 Length barrel set for M4/M16 is for you. It's all one piece which makes it easy to install and the best way to eliminate barrel wobble. Plus, it comes with a 6.03mm tight bore precision inner barrel. Buying an outer and inner barrel separately could cost over $100.00, this JBU barrel set is a steal!

I got this for my JG M16 A4 RIS. The outer barrel is very sturdy and well built. I purchased it to rid of the irritating barrel wobble in my stock version. However, the problem was that metal RIS handguard really resented this barrel. I barely got this to fit by filing down the two "fin like" exertions inside the upper half of the handguard. I also had to take the spring out of the delta ring since the handguard needs to be seated as close to the body as possible. With all this done, the front sight fits perfectly on, and everything is secure and sturdy. Disassembling/assembling the gun is now more difficult since the front sight need to be taken off first before the handguard.
I recommend this barrel to a non RIS M16.
FYI: the thread for the flash hider is 14mm CCW
The inner barrel is awesome, very light and very accurate.
