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.
  • Industrial strength, finest reinforced polymer material....nothing held back.
  • Feel the difference the second you pick it up.
  • Rock solid frame, injection molded from a fully automated system that was two years in the making.


WarrHogg 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 pistol grip area.
  • Stiffened magwell, ultra-light design.
  • See product page for additional parts list
  • Start your new 308 project now. Rifle Ideas:
  • Add an ultra-light 308 rifle to your armory
  • Superior accuracy varmint or hunting rifle
  • Hydrodip the receiver to customize
  • Competition rifle
  • Build a zombie gun, just in case
  • Prepper rifle build and stow with food

Is it legal?
YES! The 308 unit is well within the defined parameters of a "reciever 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).

Works great rigid and tough, fits well to aero precision upper. Not hard to drill out, if you have any basic talent or skills. (Posted on 9/24/2016)

Seems OK. Cosmetically it has some damage from when they threaded the bolt release pin hole. The tap and die cut some shallow threads into the side of the receiver covering about an inch outside of the bolt release. Purely cosmetic. I have not finished it yet, would like to get an xy vise to complete it. Overall I got it on sale for $90 so I'm not really complaining about the cosmetic issues. Had I paid full I would make it more of an issue. Will update further when I complete the build. (Posted on 6/7/2016)
