Overview

Built for pistol-caliber AR-15 builds, this stripped lower receiver is aimed at hunters and shooters who want a solid starting point for a 9mm or .40 S&W setup. It combines a forged 7075-T6 aluminum construction with billet-style aesthetics and several build-friendly features intended to simplify assembly at home. Details such as the threaded bolt catch pin, integrated enlarged trigger guard, threaded takedown pin detent recess, and flared magazine well make it a practical choice for a custom lower build. It is a stripped receiver, so it is best suited to builders who plan to complete the platform with their preferred components.

Key Features

  • Stripped EPC-9 lower receiver for 9mm/.40 S&W pistol-caliber builds
  • Custom-designed enhanced forging machined from 7075-T6 aluminum
  • Threaded bolt catch pin for easier installation
  • Integrated enlarged trigger guard for a more rugged build platform
  • Threaded takedown pin detent recess uses a single 4-40 set screw
  • Flared magazine well for smoother magazine insertion

Best Used For

  • At-home builders assembling a pistol-caliber AR-15 lower with simplified installation features
  • Hunters wanting a dedicated 9mm or .40 S&W lower receiver for a custom build
  • Users who prefer enhanced receiver features like a flared magazine well and enlarged trigger guard
  • Builders looking for a stripped lower with forged construction and billet-style aesthetics

Pros

  • Machined from 7075-T6 aluminum for a durable lower receiver foundation.
  • Enhanced forging offers billet-style aesthetics in a forged package.
  • Threaded bolt catch pin supports easier installation during assembly.
  • Integrated enlarged trigger guard removes fragile trigger guard tabs.
  • Threaded takedown pin detent recess simplifies detent and spring installation.
  • Flared magazine well adds a practical feature for pistol caliber builds.

Considerations & Trade-offs

  • Designed for pistol-caliber builds, so it is not a general-purpose lower for standard rifle setups.
  • As a stripped lower receiver, it requires the remaining build components and assembly work to complete the firearm.
  • The enhanced forging and integrated features may simplify assembly, but they also make this a more specialized choice than a basic lower.
  • The flared magazine well and enlarged trigger guard are build-oriented features, but they do not change the fact that this is still a stripped receiver rather than a complete lower.
