Description
The B5 SOPMOD Enhanced Mil-Spec stock represents the pinnacle of AR-15 buttstock design, combining proven military heritage with modern shooter feedback. B5 Systems engineered this stock based on the original NSWC CRANE-designed SOPMOD platform, refining every detail to meet the needs of military professionals and civilian firearm enthusiasts alike.
Key Specifications
This B5 SOPMOD stock measures 7.40 inches in length with a 4.90-inch height and weighs just 11.80 ounces, making it ideal for carbine builds where every ounce matters. The stock features color-matched steel hardware throughout, giving your rifle a cohesive, professional appearance. Its one-piece design with over-molded steel anti-rotation quick disconnect sling mounts ensures your sling stays put during tactical operations or field use. The SOPMOD Mil-Spec stock fits standard Mil-Spec carbine receiver extensions, making installation straightforward on most AR-platform rifles.
Performance & Ballistics
While stocks don’t directly impact ballistics, the B5 SOPMOD Enhanced maximizes shooter control and stability. The ergonomic cheek weld geometry provides consistent, repeatable positioning for improved accuracy. The no-slip cushioned buttpad absorbs recoil while preventing shoulder shift, critical for maintaining sight picture through multiple shots. The sure-grip stock latch prevents accidental disconnection while remaining easy to operate with gloved hands—a feature that distinguishes this design in real-world conditions.
Practical Features
The B5 SOPMOD stock ODG includes dual water-resistant storage compartments, perfect for stashing small items like batteries, cleaning patches, or emergency supplies. These compartments are sealed against moisture yet accessible when you need them. Fixed sling mounts complement the QD system, offering flexible mounting options to suit your mission profile. The Olive Drab Green finish provides authentic military aesthetics while maintaining practical camouflage in woodland environments.
Construction Quality
Built with authentic Mil-Spec materials and finishes, this B5 SOPMOD Enhanced stock undergoes rigorous testing to meet military standards. Every component, from the color-matched hardware to the molded polymer construction, is engineered for longevity. Proudly manufactured in the USA, this stock represents American manufacturing quality and attention to detail.
