Polymer80 - AR10 80% Lower Receiver Kit 

After two years of planning, design, engineering, and testing, we're proud to introduce the industry's first reinforced polymer receiver designed for the DPMS styled .308 in an 80% format. Polymer80 held nothing back in its industrial strength design using the finest reinforced polymer material.  You will feel the difference the moment you pick it up.

The .308 80% Lower Receiver  Design features:

  • Unique reinforced polymer design with solid core design
  • ATF compliant design
  • Beefed up buffer tube ring and ribbing across the entire upper surface area.
  • No-thread design on the pistol grip area.
  • Stiffened mag well, ultra-light design.
  • See product page for additional parts list

The P80 AR10 80% Lower Receiver Kit is well within the defined parameters of a "receiver blank" defined by the ATF and therefore has not yet reached a stage of manufacture that meets the definition of firearm frame or receiver found in the Gun Control Act of 1968 (GCA).

Available in Black, White, Grey, ODG, and FDE.
