Arrow cutting is provided free of charge from the Sirius Archery team. We prefer the terminology of carbon to carbon. This means please provide the physical length of carbon required for the build (this is without nock and components). Outsert components do add to your carbon length anywhere from 1/2 inch to 1 inch. This should be accounted for when you specify an arrow build.

Please write the Sirius team, or call us if you have any questions.


180gr SS Outsert system for 0.245 adds 1" to arrow build. If you want a 29" arrow, the carbon-carbon measurement is 29" - 1" = 28"


Arrow cutting should only be performed by someone trained or with knowledge of working with carbon fiber. During the cutting process, the carbon can splinter and one should be cautions working with materials. A respirator should always be used when cutting and sanding carbon fiber material
