Our take: Improve FPS and provide tighter air seal for your AEG with these NEW Black Python 509mm Tightbore Barrels by Madbull. These performance-enhanced inner barrels are precision machined from aluminum and come with a 6.03mm diameter, providing incredible accuracy and increased FPS in any AEG. Only precision grade BBs should be used with this inner barrel to avoid jamming. Measuring 509mm long, this tightbore barrel should be compatible with most hop-up systems and AEGs, especially most full length M16 series metal gearbox airsoft rifles. Professional installation is recommended for anyone unfamiliar with installing a new inner barrel. Lastly, the super slick finish strengthens and protects the barrel, which has passed through an advanced hard coating process. Maximize your AEG's performance by picking up Madbull Black Python 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- Tight air seal construction- Smooth and slick surface- Precision 6.03mm diameter- Standard M16 length barrelSpecifications:Material: AluminumDiameter: 6.03 mmWeight: 1.4 ozOverall Length: 509 mm
