Features in practical use
Bottom mount (SIG-LOC)
The mounting screws secure the sight from beneath the slide; the SIG-LOC system creates five points of contact between slide and optic.
Longer focal length
According to the manufacturer the bottom mount allows a longer focal length that reduces parallax and reticle distortion.
Enclosed and purged
The optical system is fully enclosed, sealed and purged.
MOTAC and MAGNETAC
MOTAC switches the sight off without motion; MAGNETAC automatically turns it off in a compatible holster and back on when drawn.
15 brightness settings
There are 12 daylight and 3 night vision settings; the night vision settings are optimized for Gen 3+ night vision devices (D.A.R.C.).
Side-loading battery
The CR1632 battery is changed from the side without removing the sight and without re-zeroing; runtime is up to 20,000 hours (continuous, medium setting, dot only).
Low deck height
With a height of 0.94 in (23.9 mm) the sight allows co-witnessing with standard-height iron sights.
Waterproof to IPX-7
The manufacturer rates the sight IPX-7, meaning submersion up to 1 meter.
