The Burris Optics XTR III 3.3-18x50mm Illuminated Rifle Scope is engineered for precise target engagement at extended ranges, fulfilling the demanding requirements of competitive shooters and tactical professionals. This optic integrates advanced optical design with a highly functional reticle and robust construction, providing a reliable solution for critical applications where clarity and repeatable adjustments are paramount.
Key Features
Optical System and Performance
The XTR III 3.3-18x50mm leverages an advanced optical system featuring high-definition, extra-low dispersion (ED) glass. This configuration ensures exceptional light transmission, superior resolution, and accurate color rendition across its versatile 3.3x to 18x magnification range. The 50mm objective lens mitigates vignetting and optimizes light gathering capabilities, providing a bright, clear image even in challenging lighting conditions. Edge-to-edge clarity and minimal chromatic aberration enhance target discrimination and situational awareness.
SCR MOA Reticle and Illumination
Equipped with the SCR (Special Competition Reticle) MOA reticle in the first focal plane (FFP), this optic provides precise holdover and windage references that scale accurately with magnification. The SCR MOA design is optimized for rapid target acquisition and precise shot placement without obscuring the target. Eleven distinct illumination settings, including intermittent “off” positions between each setting, allow for precise reticle visibility adjustments across a broad spectrum of ambient light environments, from bright daylight to low-light conditions.
Precision Adjustment System
The XTR III features exposed, tactical-style elevation and windage turrets with a 1/4 MOA click value, delivering precise and repeatable adjustments. The turrets incorporate a tool-less zero stop mechanism, facilitating rapid return to an established zero after making significant elevation changes for long-range engagements. Generous total adjustment ranges for both elevation and windage accommodate a wide array of cartridge ballistic profiles and engagement distances. A side parallax adjustment knob, ranging from 20 yards to infinity, allows for precise image focus and reticle-to-target alignment, eliminating parallax error.
Robust Construction and Durability
Constructed from a single piece of aerospace-grade 34mm aluminum, the XTR III chassis provides exceptional structural integrity and recoil resistance. The optical system is nitrogen-purged to prevent internal fogging due to temperature fluctuations, and all external lenses are treated with Burris’ proprietary anti-scratch coatings. This scope is rigorously tested to ensure it is waterproof, fogproof, and shockproof, maintaining operational reliability under harsh field conditions and sustained use.
