POLYMER80 UNIVERSAL MULTI-USE AR-15 80% LOWER RECEIVER JIG
MPN: P80-RJ556U-JIG

** Will work with P80 Phoenix G150, P80 Rhino and Aluminum Mil-Spec AR-15 lowers.
*** May NOT work with Billet lowers that are larger than Mil-Spec dimensions.

The P80 Universal Jig is dimensionally the same as the "Rhino" jig but made from a different material that produces a much harder surface.

The "Universal" jig is capable of completing 3-5 lowers if used properly. Keep in mind, it is made from a proprietary blend of nylon and plastic and can still be damaged if used or drilled incorrectly.


Includes:

  • Finishing Jig
  • Trigger Guide

5 of 5 Looks and works great! April 30, 2025
: Doug Graham from LEWISTON , ID United States  
I purchased a Polymer80 lower, with the intent of building my own AR-15 from scratch. The jig fits the lower perfectly. Now, all I need is a drill press to actually mill out the fire control pocket. Overall, I'm pleased with my purchase!

5 of 5 Much better July 9, 2024
: from Janesville, WI United States  
Haven't used it yet, but just received mine in the mail with an aluminum lower and an thoroughly impressed with it.  Much thicker, sturdier, and heavier than the normal orange ones.  A version made of steel or with steel hole and pocket guides would be awesome.
