Features in practical use
Solar cell and battery
The solar cell on the housing supports the battery; the manufacturer states runtimes in excess of 100,000 hours with solar and battery use. The CR2032 battery is changed from the side without tools.
Four selectable reticles
You can choose between dot, circle dot, dot with holds and circle dot with holds. The dot measures 2 MOA, the circle 65 MOA, and the holds are at 5, 9 and 15 MOA.
MOTAC and 12 brightness settings
The sight switches off after 120 seconds without motion and back on when it senses movement. There are 12 brightness settings, 10 for daytime and 2 for night vision.
Mounting for M1913 rails
A 1.41 in (about 36 mm) riser mount with a 1/2 in hex bolt for absolute co-witness with iron sights and a low profile Torx mount are included.
7075 aluminum, IPX-8
The housing and components are made of 7075 aluminum. The manufacturer lists IPX-8 waterproofing (submersion up to 20 meters) and MIL-STD-810G testing.
Unlimited eye relief
The sight has no fixed eye relief and ultra-low parallax, so the aiming point can be acquired from any head position behind the sight.
