Overview

Built for AR-15 setups that need a stable, streamlined shoulder interface, this stock combines an ergonomic cheek weld with a no-slip cushioned butt pad and sure-grip latch for controlled handling. It also includes overmolded steel anti-rotational QD sling mounts, fixed sling mounts, and dual storage compartments, giving it practical utility without adding unnecessary complexity. The polymer construction and Coyote Brown finish keep the look consistent with other B5 Systems color options, while the fit is intended for Mil-spec AR-15 receiver extensions. Tube is not included, so it suits builders or owners replacing an existing compatible setup.

Considerations & Trade-offs

  • Tube not included, so this is a stock-only purchase and requires a separate Mil-spec AR-15 receiver extension.
  • Designed for Mil-spec AR-15 receiver extensions only, so compatibility depends on the buffer tube already on the rifle.
  • Dual storage compartments add utility, but they also make this a more feature-focused stock than a minimal setup.
  • Polymer construction and fixed sling points keep the design straightforward, but the product is centered on function rather than adjustable stock features.
