Key Features
Precision Optical System
The XTR III features a sophisticated optical design utilizing index-matched, Hi-Lume® multi-coatings on all air-to-glass surfaces. This system optimizes light transmission, mitigating glare and maximizing contrast, even in low-light environments. The expansive 56mm objective lens ensures a bright, sharp image across the entire 5.5-30x magnification range, providing critical target detail at extended distances.
First Focal Plane (FFP) Illuminated SCRMIL Reticle
Equipped with an Illuminated SCRMIL reticle in the first focal plane, the XTR III allows for accurate ranging, holdovers, and windage corrections at any magnification setting. The reticle scales proportionally with magnification, maintaining consistent subtensions. Illumination is controlled with an intuitive turret, offering multiple intensity settings to ensure optimal visibility against any background without over-saturation.
Robust Construction and Ergonomics
Constructed around a durable 34mm main tube from aircraft-grade aluminum, this scope is designed to withstand the rigors of field use and repeated recoil. The robust mechanical design ensures consistent tracking and return-to-zero capability. Low-profile, tool-less zero click stop elevation and windage turrets provide positive, tactile feedback for precise adjustments, critical for rapid target engagement and follow-up shots.
Reliability and Durability
The XTR III is internally purged with dry nitrogen and sealed to ensure absolute waterproof and fogproof performance, even in extreme temperature fluctuations. Its shockproof construction guarantees durability against impacts, maintaining optical integrity and point of impact under demanding operational scenarios.
