The machined version of the Caliburn is, generally, stronger and as a smoother function.
The barrel can be swapped out with any barrel with a 5/8″ OD making the machined version more versatile. If your darts are skinnier, swap in a CPVC barrel, if they’re wider, swap in a PETG barrel or even an aluminium one.
If you want a specific barrel material, please make note.
Options include clear, white, spring power, and barrel material.
Includes two attachment points for two point slings.
