Overview

Built around Bravo Company’s BCM4 lower receiver configuration, this complete lower is set up for a serious AR-15 build with a focus on control and modularity. It includes a BCM Mod 2 SOPMOD stock, BCM Mod 4 pistol grip, BCM enhanced trigger guard, and BCM PNT semi-auto trigger, along with a QD sling mount end plate and three rear sling mounts. The Mk2 receiver extension is listed as approximately 3/4" longer than carbine length and uses an 8-position, mil-spec diameter setup with the MK2 Mod 1 - T0 buffer.

Pros

  • Mk2 receiver extension provides an approximately 3/4-inch longer setup than carbine.

  • Three rear sling mounts and a QD sling mount end plate are included.
  • Configured as a complete widebody lower from Bravo Company.

Considerations & Trade-offs

  • Complete lower assembly with a widebody configuration, which means it is more specialized than a standard stripped lower and should be evaluated against your intended setup before purchase.
  • Uses the Mk2 receiver extension, which is approximately 3/4" longer than a carbine extension, so stock fit and overall feel will differ from a conventional carbine-length setup.
  • Configured with BCM-specific components and upgrades, so replacement or future changes may be more brand- and model-specific than with a basic lower build.
  • Caliber is listed as MULTI, but the product data does not provide additional caliber-specific setup details, so compatibility should still be confirmed against the rest of the rifle system.
