The RITON 3 Primal 3-9×40 EER rifle scope is engineered to optimize precision and adaptability, providing a decisive advantage for experienced shooters. Its Extended Eye Relief (EER) system is a key operational feature, contributing to improved comfort, faster target acquisition, and heightened situational awareness during field applications.
Key Features
Extended Eye Relief (EER) System
The 3 Primal 3-9×40 EER incorporates an Extended Eye Relief system, specifically designed to maintain a consistent and generous eye box. This configuration mitigates the risk of scope bite from heavy recoil, facilitates rapid target acquisition, and provides greater flexibility in mounting options, accommodating various stock geometries and user stances while ensuring full field of view with safety glasses.
Precision Optical System
This optic integrates a 3-9x variable magnification range with a 40mm objective lens to deliver a clear and high-contrast sight picture critical for precise engagement. Lenses are fully multi-coated to maximize light transmission across the visible spectrum, thereby enhancing brightness and maintaining accurate color rendition in sub-optimal lighting conditions. The optical system is calibrated to ensure consistent performance throughout the magnification range, minimizing optical aberrations.
Robust Construction
Constructed from a single piece of 6061-T6 aircraft-grade aluminum, the 3 Primal 3-9×40 EER chassis offers superior durability and resistance to environmental and operational stressors. The scope is nitrogen purged and O-ring sealed, guaranteeing complete waterproof and fogproof performance across diverse climatic conditions. This construction integrity ensures the optic sustains repeatable zero and reliable function under repeated recoil and impacts.
Second Focal Plane (SFP) Reticle
The Second Focal Plane (SFP) reticle design ensures the reticle maintains a constant perceived size irrespective of the magnification setting. This architecture simplifies holdover and windage corrections for operators who primarily utilize the reticle at a specific magnification, allowing for precise subtension values at either the highest power for detailed engagement or the lowest for rapid, close-range target acquisition.
