A3 Tactical HDA3 Hybrid Polymer Stock – Universal 1913 Picatinny Mount

The A3 Tactical HDA3 Hybrid Polymer Stock brings lightweight ergonomics and rugged durability to any platform with a rear 1913 Picatinny interface. Combining a high-strength injection-molded polymer stock body with an aluminum mounting core, the HDA3 features a built-in cheek weld and a textured buttpad for fast target acquisition and recoil control. Equipped with an integrated anti-rotation QD sling socket and available with A3’s positive-locking folding hinge, it provides a sleek, low-profile shoulder option for sub-guns, PCCs, and compact rifles.

Key Features & Highlights

• Hybrid Construction: Features a impact-resistant, high-density polymer stock housing surrounding a machined aluminum mounting skeleton for maximum structural rigidity without extra weight.
• Universal 1913 Picatinny Interface: Attaches directly to any rear 1913 Picatinny rail with a secure single-screw clamp setup, making it an easy bolt-on upgrade for platforms like the SIG MCX/MPX, CZ Scorpion, AK-1913 adapters, and AR-pistol conversions.
• Ergonomic Cheek Weld: Contoured top profile ensures comfortable cheek position and natural sight alignment for both iron sights and raised red dot mounts.
• Integrated Anti-Rotation QD Socket: Includes a built-in Quick Disconnect sling attachment point on the lower portion of the housing to prevent sling twist during movement.
