BMPS Tight-Bore Machined Aluminium Anodised Barrels

BMPS Tight Bore Foam Dart Blaster Barrels are made with custom tooling to the ideal dimensions for maximum foam dart blaster performance. They feature a consistent 12.75mm inner diameter for the optimal seal for maximum FPS with 13mm diameter darts, and a 16.0mm outer diameter, compatible with a wide range of blasters including BMPS Zinc variants.

The clear-anodisation inside and out provides a premium finish, offers less resistance against dart acceleration, and ensures a smooth air seal on the dart. 

One end, intended to be the rear/dart-entry end, has a large internal shallow (30°) chamfer for easy alignment with pusher O-rings. The other end, intended to be the front/dart-exit end, has a smaller 45° chamfer to ensure thorough deburring.

Please note that the tight bore may not be beneficial with lower performance blasters with longer barrel lengths, as the additional drag may outweigh the additional air sealing on the dart provided by the tighter bore.
