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. Outer tube walls are 25% thicker for 42% greater 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 1X-4X XTR ? equipped with the innovative XTR Ballistic 5.56 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.
