Burris Optics 3-12x50mm XTR Xtreme Tactical Series Riflescope, Matte Black Finish with Illuminated Mil Dot 12x Reticle, XT-1 Knobs & Side Parallel Adjust, 30mm Tube

XTR XTREME TACTICAL RIFLESCOPES:
• Burris has gone to extremes to engineer the ultimate in high-performance optics XTR Xtreme Tactical Riflescopes. Extra-large, ultra-premium lenses produce unsurpassed resolution, clarity, and brightness.
• Index-matched HiLume multicoating boosts clarity and, enhanced with new StormCoat, causes water to bead and shed off for a clearer view when water drops are present. All XTR scope tubes are 30mm, resulting in 25% thicker main tubes and 42% more strength. Double-force coil spring suspension locks the inner tube in place for unfailing accuracy. XTRs also feature side turret-mounted parallax adjustment systems. LRS models have a fully integrated side turret-mounted illumination system. The new 1.5x-6x XTR equipped with the innovative XTR Ballistic 7.62 Reticle represents the state of the art in tactical optics.
• The whole package is waterproof, fogproof, shockproof and warranted forever. Tactical scopes just don't come any better.

• The XTR 12x Ballistic Mil-Dot Reticle is designed specifically for the military-standard 7.62 NATO (.308Win) round. Designed for the center crosshair to be sighted in (zero'd) at 100 meters, then each additional ballistic line below center represents 100 meters in additional target distance. The ammunition that the XTR Ballistic Mil-Dot Reticle is calibrated for is the 7.62 NATO (.308WIN) 175GR HPBT Matchking @2600FPS. By design, this same calibration is nearly identical to the 5.56 NATO (.223Rem) 77GR HPBT Matchking @ 2750FPS out to 500 meters.
