Looks interesting, please keep us informed if you get one (or two).
EDIT: I contacted Vortex via email, to find out where the emitter is, it is at 6 o'clock position, not a good place for co-witness.
The Vortex SPARC co-witnessed nicely on the AR that we had to test but I didn't get a chance to really look closely at the Benelli set-up. I'll probably know more after this weekend.
What is the battery life on it?
I found some data on the Vortex SPARC
Aircraft-grade 6061-T6 aluminum body. [Note: The versatile multi-height mount system of the SPARC accommodates AR15s needing absolute or lower 1/3 co-witness heights and uses a standard Weaver or Picatinny base (not included). The SPARC is also threaded to accept accessory ARD and comes with a 2x doubler.]
It takes a SPARC to light a fire:
•Fully multi-coated lenses increase light transmission with multiple anti-reflective coatings on all air-to-glass surfaces
•1-Pc. tube maximizes strength and waterproofness
•High recoil caliber rating... tested with .375 H&H Magnum for 1000 rounds
•Adjustable dot intensity provides ten variable illumination settings to increase or decrease dot brightness according to viewing conditions
•Night vision mode sets the brightness to the lowest possible level... will work best with most night vision devices
•Unlimited eye relief provides maximum mounting options
•Parallax free... allows for rapid shooting with both eyes open without concern for parallax shooting error. Parallax free beyond 50 yards; one-inch error closer than 50 yards
•Screw-in doubler provides extra magnification for longer distance shooting
•6-hour auto-shutdown feature maximizes battery life: 120 hours (maximum brightness), 3400 hours (minimum brightness). Typical battery life in night vision mode: 4200 hours (maximum brightness), 4600 hours (minimum brightness).
•Risers and shims combine in various ways to mount the SPARC at four different heights
•Optics are sealed with O-rings to prevent moisture, dust, and debris from getting inside the scope
•Rated from -40 degrees to +140 degrees Fahrenheit
•Tube size: 22 mm
•Dot size: 2 MOA
•Adjustment graduation: 1 MOA / Click; 45 MOA / Rotation
•Max elevation adjustment: 90 MOA
•Max windage adjustment: 90 MOA
•Parallax setting: Parallax free past 50 yards
•Weight: 5.2 ozs.
