Orca Reinforcement Kit


Out of stock

This kit contains all of the reinforcement parts needed to complete an Orca 3D printed AR-15.

You will need to provide all of the AR-15 parts, and print all of the primary components. The Clips, Barrel Mount, and Hose Clamp Covers are included in this kit. These are the parts best printed in filaments other then PLA+. Hence, you will be able to complete the Orca even if PLA+ is all you can print.

Two bags are included for each kit. One includes the printed parts and the other the hardware parts.

  • (2) barrel mount clamshells.
  • (12) Clips. Four of these are spares. Spares not shown in photos.
