Description

Minimal Flex. Maximum Stability. Engineered for Precision-Centric AR Builds.
The Hera Arms HRS Fixed Buttstock in black is a fiber-reinforced, rifle-length stock system developed for AR-15 and M4 platforms requiring long-range rigidity and uncompromising rear-end stability. Optimized for compatibility with A2-spec rifle buffer tubes, the HRS eliminates the play and flex commonly found in collapsible stocks—making it ideal for precision-driven builds, DMR configurations, and high-round-count training rifles. Weighing just 13.7 ounces, the HRS offers a strength-to-weight ratio ideal for shooters who prioritize system balance without compromising material integrity.

Storage-Capable, Modular Housing with Integrated Sling Points
Both side panels of the HRS are removable and double as internal storage compartments for field spares such as CR123A batteries or small tools—without affecting balance or profile. Molded QD sling sockets on either side of the stock accept ball-lock sling swivels, ensuring secure retention for patrol-ready or sling-supported shooting setups.

Optimized Interface for A2 Buffer Geometry
The HRS is precision-molded to fit all rifle-length A2 buffer tubes, and is also compatible with any lower receiver that follows standard AR-15 buffer extension geometry. No adapters or spacers required—installation is direct, and lockup is solid.

Color-Matched for Platform-Specific Builds
This model is available in black for duty or minimalist builds, as well as FDE tan and OD green to match rifle systems optimized for arid, urban, or transitional terrain.
