This configuration
This version is the ROMEO8T-AMR in black without a magnifier.
Features in practical use
AMR: Automatic Modified Reticle
With an AMR-capable magnifier the sight stores reticle and brightness separately for magnified and non-magnified use and switches automatically when the magnifier is flipped in or out.
40 mm lens
The multi-coated 40 mm Mangin lens provides a wide field of view and makes it easier to pick up the aiming point.
Quad Ballistic Circle Dot 2.0
The reticle offers four selectable variants with dot, circle and ballistic holds, optimised for day, night and extended range.
15 brightness settings and NV override
Of 15 settings, 3 are optimised for passive night vision. A dedicated NV button toggles maximum brightness; D.A.R.C. is tuned for Gen 3+ night vision devices.
CR123 and MOTAC
The CR123 battery combined with MOTAC lasts more than 50,000 hours according to the manufacturer. MOTAC switches off after 2 minutes of inactivity and on again on movement.
Compact and light
Compared with the original ROMEO8T the manufacturer states a size and weight reduction of more than 30 percent.
