We wanted to bring an aesthetically pleasing, unique and functional billet lower to the market, while keeping the price near the same as a forged lower. This is the answer to that request. Priced cheaper than the majority of billet lowers out there, with better options.
  • Captured Takedown Pin Spring (threaded hole with hardware)
  • Left side of safety selector hole notched out for BAD_ASS ST 45 degree short throw levers to drop in with no modifications – Engraving will also accommodate 45 degree (BAD) 60 degree (Noveske) and 90 degree (Standard) selectors
  • Upper tensioning screw behind pistol grip screw (threaded hole with hardware) to adjust any “slop” out of vertical fit between upper and lower
  • Ambi trigger finger rests with grooves (above and below mag release / mag catch)
  • Compatible with Norgon and other aftermarket ambi mag releases
  • Threaded bolt catch pin (Threaded hole and hardware)
  • Drop free magwell design with beveled bottom lip
  • Front of magwell traction/finger grooves
  • Integrated large opening trigger guard
  • Accepts all standard LPK’s, KNS pins, etc, etc….

    This is a great billet lower. I love the threaded captured take down spring and trigger finger rest. I recieved great service from the owner, and will be back for my next build.

  4. Brian (verified owner)

    Great receiver to build on. The fit and finish is on par or better than receivers twice the price. I am very impressed and these will be my go to lower for future builds. I just wish there was a matching 308 set.
