You've waited for it and Burris has delivered.  A true tactical scope for semi-auto .308 (7.62mm) tactical rifles like the AR-10 and others.  You wanted the .308 for the knock down power and extended range.  This scope gives you what you want.... 1.5x for close range work up to 6x for long range precision.  I just can't think of a more effective scope for your .308 semi-auto tactical rifle.

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.
