    Our take: These NEW 300mm Ultimate Tightbore Barrels by Madbull provide the tightest air seal an AEG, ultimately improving muzzle velocity and performance. These enhanced inner barrels are precision machined from aluminum and sport a 6.01mm diameter, providing maximum accuracy and increased FPS in any AEG. Only precision grade BBs should be used with this inner barrel to avoid jamming. Measuring 300mm long, this tightbore barrel should be compatible with most hop-up systems and metal gearbox airsoft guns. Professional installation is recommended anyone unfamiliar with installing a new inner barrel. Lastly, the super slick finish strengthens and protects the barrel, as well as minimizing overall friction. Maximize your AEG's performance by picking up Madbull’s Ultimate Tightbore Barrel today! NOTE: This inner barrel is ready to use right out the packaging, though professional installation is recommended or may be required. Please only use high-quality precision seamless BBs in your airsoft gun after installing this barrel, as inferior grade BBs (i.e., ones from sporting goods stores) WILL jam inside this barrel. Features: - CNC machined aluminum - Precision 6.01mm diameter - Tight air seal construction - Smooth and slick surface - Hard anodized coating - Titanium color finish - Compatible with all AEGs with 300mm inner barrels Specifications: Material: Aluminum Alloy Diameter: 6.01 mm Weight: 0.8 oz Overall Length: 300 mm
