Overview

Built for a complete AR-15 lower setup, this Bravo Company BCM4 configuration brings together a multi-caliber receiver, a PNT semi-auto fire control group, and a BCM Mod 2 SOPMOD stock in an FDE finish. It is set up with the Mk2 receiver extension, MK2 Mod 1 - T0 buffer, BCM Mod 4 pistol grip, and BCM enhanced trigger guard, along with three rear sling mounts and a QD sling mount end plate. The included Mk2 RMS recoil mitigation system and other BCM upgrades make it a practical choice for hunters and shooters who want a ready-to-use lower assembly with a more refined control package. Its complete format is well suited to a build where consistency, sling options, and a familiar BCM setup matter more than starting from individual components.

  • Includes BCM Mod 2 SOPMOD stock for a factory-built lower setup.

Considerations & Trade-offs

  • Configured as a complete lower, so it is less flexible for hunters who want to choose every component individually.
  • The Mk2 receiver extension is approximately 3/4" longer than a carbine extension, which may affect setup preferences and stock feel.
  • This is a widebody lower with BCM-specific components, so compatibility and ergonomics are more specialized than a basic stripped lower.
  • The product data does not include complete dimensional details for the assembled unit, so fit expectations should be verified against the intended build.
