Overview
The Ruger Single Six provides a robust and adaptable platform for both cost-effective training and small game applications. This single-action revolver integrates the capacity for both .22 Long Rifle and .22 Magnum cartridges via its convertible cylinder system, delivering practical utility across varied shooting requirements. KFF Defense recognizes the Single Six as a reliable instrument for shooters who demand consistent performance and material durability.
Key Features
Convertible Cylinder System
The hallmark of the Single Six is its dual-cylinder capability. Chambered to accommodate both .22 Long Rifle and .22 Magnum ammunition, this system optimizes the revolver for a spectrum of uses, from economical practice with .22LR to enhanced terminal performance with .22 Magnum. Cylinder interchangeability is a straightforward, tool-less operation, maximizing its operational versatility.
Robust Stainless Steel Construction
Constructed from high-grade stainless steel, this Single Six variant is engineered for superior longevity and resistance to environmental corrosion. The material selection contributes to the revolver’s inherent strength and structural integrity, ensuring consistent function under demanding field conditions. This construction mitigates wear and maintains critical tolerances over extended periods of use.
Precision Single-Action Mechanism
The single-action operation mandates manual cocking of the hammer for each shot, facilitating a deliberate and consistent trigger pull. This design inherently promotes precision shot placement, a critical attribute for competitive plinking, target acquisition, and precise small game hunting. The mechanism is engineered for reliable cycling and consistent primer ignition.
Adjustable Sights
Equipped with adjustable sights, the Single Six allows for precise elevation and windage modifications. This feature is critical for zeroing across different ammunition types and ranges, enabling the operator to optimize point-of-impact to point-of-aim. The sight picture is designed for rapid acquisition and clear discrimination of targets.
