    Our take:  JBU's inner barrels are made from high tensile, aircraft grade aluminum, using precision CNC machining. These JBU 6.01mm tight bore inner barrels provide maximum accuracy and increased FPS in any AEG. Because these barrels are precision crafted, only high quality, precision grade BBs should be used with this inner barrel. The JBU Tight Bore 6.01mm barrel should fit in most AEGs, and should be compatible with most hop up systems. Professional installation is recommended for anyone unfamiliar with installing a new inner barrel.

    The super slick performance finish strengthens and protects the barrel, while reducing friction (conserves velocity & back spin).  This 363mm barrel fits most M4-A1, SR-16, M15, Sig 551, and M249 metal gearbox AEGs.

    Precision manufactured to ensure durability and high quality.

    Note:  Ready to use right out of the box, though professional installation is recommended/may be required.  Please use only ultra high-quality precision seamless BBs in your gun after installing this barrel, as inferior grade BBs (i.e. BBs from sporting goods stores) WILL jam inside this barrel.

    "I used this tightbore barrel to upgrade my D-Boys M4 S-System and it works well, it has greater range and accuracy now which my friends do not enjoy. Be careful though that you dont get too long of an inner barrel otherwise it'll stick out the end of the gun and it looks really ghetto so get a barrel extension just in case, or a mock suppressor or tracer unit."
