Burris XTR III 3.3-18x50 Riflescope 34mm Tube Illuminated SCR2

The Burris XTR III 3.3-18x50 delivers precision optics for long-range shooting with its 34mm main tube and advanced SCR 2 reticle system. This riflescope bridges the gap between tactical applications and precision hunting with features engineered for consistent performance across varied shooting conditions.

What Makes This Different

The 34mm main tube provides 30% more internal adjustment range compared to standard 30mm tubes, allowing for extreme long-range corrections without external mounts. The SCR 2 reticle features illuminated center elements with precise holdover points calibrated for modern ballistics. Advanced multi-coating reduces light loss to just 8% per lens surface, maintaining clarity even in challenging lighting conditions.

Key Features

• 5.45x magnification range (3.3-18x) covers close quarters to 1,000+ yard engagements
• 50mm objective lens gathers maximum light for dawn and dusk shooting
• 34mm monotube construction machined from single piece of aircraft aluminum
• SCR 2 reticle with illuminated center dot and precise mil-based holdovers
• Side focus parallax adjustment from 50 yards to infinity
• Capped turrets with 0.1 mil clicks and zero-stop mechanism
• Nitrogen purged and O-ring sealed for complete waterproof performance

Field testing demonstrates consistent tracking through temperature extremes from -20°F to 140°F without point-of-impact shift. The scope maintains zero through heavy recoil cycles on magnum cartridges and withstands shock equivalent to 1,000 G-forces. Low-light performance excels during twilight hours when game movement peaks, while the illuminated reticle remains visible without washing out the target image.
