Double Rib AR-15 Reinforcement Kit

(2 customer reviews)


This kit contains the reinforcement parts needed to complete a 3D printed Double Rib AR-15 Super Lower. Please keep in mind that this kit will only work with the double rib lower, it will not work with the new SL-15.

You will need to provide all of the AR-15 parts, and print the lower itself. If you want a more complete kit, check out the Double Rib AR-15 Combo Kit.

Included in this kit:

  • Four Bushings.
  • Bushing Installation Tool
  • Front Plates.
  • Two 10-32 Nuts.
  • Two 10-32 x 1.25″ Screws
  • Large Hose Clamp.
  • Hose Clamp Cover.
  • 1/4-20 Brass Insert.
  • 1/4-20 x 1.125″ Screw.

And that is everything in the kit! For more info, check out the Super Lower download on the Downloads Page.
