Polymer80 AR15 80% Receiver w/ Jig Kit

Out of Stock

Polymer80's original polymer AR-15 80% lower and jig kit are back! This AR-type lower is a simpler, more affordable version of P80's upgraded "RHINO" RL556V3 80% lower. This lower provides the same, exact functionality and capability when it comes to building a custom AR-15.

The Polymer80 AR-15 80% lower works with mil-spec lower parts kits, standard buffer assemblies, and regular forged or billet AR-15 upper receivers and barreled assemblies.

Includes Jig and Tooling

The Polmyer AR-15 80% lower is convenient for new users because it includes the required 80% jig and bits. This polymer combo kit's the perfect way to dive into the world of at-home gunsmithing: Polymer's easier to cut and drill, but the assembly and final build will look and perform just like any other AR-type rifle or pistol.

Polymer 80% Lower & Jig Features:

  • Made from glass-reinforced nylon polymer
  • Compatible with "retail", mil-spec AR parts
  • Includes jig and tooling for completing lower
  • Provides templates for drilling and cutting
