B5 Sopmod Stk Mil-spec

The B5 Sopmod Stk Mil-spec is a mil-spec fixed buttstock engineered to AR-platform rifles for shooters requiring a compact, reliable cheek weld and storage capability. Designed to mil-spec dimensions and established for compatibility with standard AR buffer tubes, this stock delivers the ergonomic profile favored by tactical operators, law enforcement, and competitive shooters who prioritize accessibility and modularity in their rifle setup.

The mil-spec footprint ensures drop-in compatibility with any mil-spec receiver extension and minimizes fitment variables during assembly. The fixed design eliminates play and potential for unintended movement under recoil or during dynamic transitions—a critical advantage in duty and training environments where stock integrity directly affects cheek position and sight picture consistency. The integrated compartment accommodates field gear, batteries, or emergency supplies without adding external bulk or weight to the rifle profile.

This stock serves operators building duty rifles, home defense platforms, or precision rifles where a compact, non-adjustable design is preferred over collapsible alternatives. The mil-spec configuration also suits builders who value standardization across multiple platforms or those working within armory specifications that mandate mil-spec components. Its straightforward design reduces maintenance points and delivers consistent performance across a wide temperature and deployment range.
