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 whole package is waterproof, fogproof, shockproof and warranted forever. Tactical scopes just don’t come any better.
