Features in practical use
Enclosed system
The full-length steel shroud with sealed rear window turns the reflex sight into an enclosed system and protects the emitter from dust, debris and moisture.
7075 aluminium housing
The housing is made of CNC 7075 aluminium; the steel shroud has a Melonite treatment.
15 brightness settings
The dot offers 15 brightness settings, 12 for daylight and 3 for Gen 3+ night vision devices (D.A.R.C.).
MOTAC and MAGNETAC
MOTAC switches the dot off after 2 minutes without motion and back on when movement is detected. MAGNETAC switches the sight off in a compatible holster with a magnet and on again when drawn.
Side battery tray
The CR2032 battery is changed through a tray on the side without removing the sight from the firearm. The manufacturer states up to 25,000 hours of runtime at medium brightness.
PRO footprint
The sight shares the ROMEO1PRO footprint and mounts directly to Sig pistols with the PRO or R2 slide cut.

Twin adjustment springs are designed for handgun recoil; elevation and windage move by approximately 1 MOA per click.
