JBU (JB Unicorn) Tightbore Barrrels
![]() |
Tightbore Inner Barrels by JB Unicorn (JBU) The gun applications listed below are the most common use of that barrel length. Some versions may use different length barrels. If you are unsure what length barrel you need, please contact us prior to ordering. We will be happy to assist you in picking out the correct barrel for your needs. They are constructed of hard anodized aluminum to provide a lightweight, rigid, smooth bore barrel for increased range and accuracy. *Please Note: The 6.01mm diameter barrels are designed with the experienced airsofter in mind and should only be used if you are willing to maintain the barrel. The barrel should be cleaned before and after each use and only the highest quality BBs should be used. Failure to maintain the barrel and/or use high quality BBs will result in jams due to the tight tolerances to which these barrels are manufactured and could result in damage or scoring of the barrel. Use with caution. NOTE: AEG Barrels will not work with VSR Series guns unless you install a special adaptor in your VSR. ![]() ![]() ![]() ![]() ![]() |
