B5 Systems SOPMOD Government Mil-Spec Stock, FDE SOP-13 - Premium Tactical Upgrade
- Finish-Color:
- Black
The B5 Systems SOPMOD Government mil-spec stock is a battle-proven AR carbine upgrade with serious pedigree. Since 2011, B5 has manufactured this design for the US Department of Defense, and now it's available to civilian shooters and builders who demand gear that's seen real use. If you're building or upgrading an AR platform rifle for hunting, duty, or precision work, a quality stock makes a tangible difference in control and comfort—and the SOPMOD delivers on both fronts with a design born from military specifications.
Built to mil-spec standards and proudly manufactured in the USA, this stock combines practical features that work whether you're behind the gun at the range or in the field. The ergonomic cheek weld promotes a consistent sight picture, while fixed sling mounts and color-matched steel hardware integrate cleanly into your setup. The no-slip cushioned butt pad stays put under recoil and provides a secure shoulder anchor, and the dual water-resistant storage compartments let you stash small essentials—batteries, elevation notes, or range dope—without adding a separate pouch.
This FDE (Flat Dark Earth) variant pairs with mil-spec AR carbine receiver extensions. Whether you're running a 16-inch patrol rifle, a lightweight hunting build, or a precision competition setup, the SOPMOD's proven ergonomics and no-nonsense construction earn it a spot on working guns across the country. It's the kind of upgrade that doesn't demand attention—it just works.
