Tightbore Inner Barrels by Mad Bull
Black Python 6.03mm: The MadBull Black Python 6.03mm tightbore inner barrels are available in a variety of sizes to fit most applications. Constructed of lightweight, anodized aluminum for a stiff, smooth bore to increase range and accuracy.
The applications listed below are the most common for that barrel length. However, some versions of those models may use slightly different lengths. If you are unsure of what length barrel you need, please contact us prior to ordering. We will be happy to help you pick out the right barrel for your application. Ultimate Tightbore 6.01mm: The MadBull Ultimate Tightbore inner barrel is made of 7075 aircraft aluminum alloy with a titanium colored anodized coating to ensure the tensile strength and hardness of barrel. 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. MadBull Crawler Barrel: A low cost way to quickly reduce the fps of your AEG without sacrificing accuracy. The MadBull Crawler is specially ported to bleed off air pressure which can result in a 30-100 fps drop in your overall velocity. Results will vary and are directly related to the original fps of your gun and overall condition of the AEG. Available on 300mm only. Combine the Crawler with a separate hop-up chamber, and you have a relatively simple drop in solution when going to a CQB or other field with reduced fps limits. NOTE: AEG Barrels will not work with VSR Series guns unless you install a special adaptor in your VSR.
