The Hera HRS Fixed Buttstock in Black is a purpose-built replacement stock designed for AR-15 and M4 carbines equipped with standard A2 rifle buffer tubes. Manufactured from fiberglass-reinforced polymer, this fixed buttstock delivers a proven platform for operators who prioritize simplicity, modularity, and storage capability over adjustability. The HRS (Hera Rifle Stock) integrates seamlessly into any rifle system using A2 tube geometry, making it a straightforward retrofit option for both new builds and field-proven platforms.
The fixed buttstock design eliminates mechanical complexity—no springs, detents, or adjustment mechanisms to fail in the field. The polymer composite construction resists corrosion and environmental degradation, critical for sustained deployment in harsh conditions. Weight of 1.06 lbs keeps the stock light without sacrificing rigidity. Removable cover panels provide discrete storage compartments ideal for carrying battery cells, tritium inserts, or field-essential items without adding external pouches or bulk to the carbine profile.
The Hera HRS suits operators and shooters who run fixed stocks for consistency, duty weapon configurations prioritizing reliability over ergonomic adjustment, or AR platforms built to specific length-of-pull requirements. Law enforcement carbine programs, precision riflemen using bench-configured setups, and close-quarters tactical teams benefit from the locked, repeatable cheek weld. Installation requires no specialized tools—standard AR armorer procedures apply. Compatible with any upper receiver assembly on A2-tubed lowers, the HRS buttstock is a no-compromise alternative for shooters who understand that fixed geometry solves operator variability at the source.
