ORCA AR-15 Build Kit


The Orca is an AR-15 rifle with a 3D printed upper and lower system. It is a preeminent member of a new generation of printed ARs that support printing the upper receiver as well as the lower. The goal of the project is to print as much of the AR-15 as possible, without compromising the performance.

The following components that would be on a factory AR-15 have been replaced by printed or non-firearm parts, or made unnecessary:

  • Upper
  • Lower
  • Handguard
  • Buffer tube
  • Barrel nut
  • Stock
  • Grip
  • Takedown pins
  • Buffer retainer

The Orca design has been extensively tested by the guncad community and has proved its worth. Purchase this kit to obtain all parts required to build an Orca of your own.
