This is a limited edition dart barrel from darts shop R. It's rare because it can only be purchased at the store. I had it as a spare, so it's in good condition. The photo shows an example setup. Barrel only will be sent. ■ Product Specifications Material: 90% Tungsten Length: 37.1mm Max Diameter: 6.9mm Barrel Weight: 16.5g Shape: Torpedo Cut: Ring Cut Standard: 2BA
