The Holosun HE507C X2 with the ACSS Vulcan reticle, part number HE507C-GR-X2-ACSS, is a 1x open reflex pistol sight on the Holosun 507C footprint, which is the Trijicon RMR pattern.
A chevron is not a dot with corners. Its tip is a single point you can hold with, while the circle around it pulls the eye to that point before you have consciously found it.
Holosun machine the housing from 7075-T6 aluminium in a hard anodized black finish and rate it IP67 against water and dust, at 1.5 oz (43 g) with a 0.63 x 0.91 in (16.0 x 23.1 mm) window. A CR1632 cell sits in a side-loading tray so it can be changed with the sight still bolted down and zeroed, rated to 50,000 hours, with Solar Failsafe taking supplemental power from ambient light and Shake Awake sleeping the reticle when nothing has moved.
The green LED runs 12 brightness settings, ten daylight and two night-vision compatible, and the eye reads green more brightly than red at the same output, which tells in woodland and against dark ground. Adjustment is 1 MOA per click with plus or minus 50 MOA of travel and the sight is parallax-free. The reticle is fixed at a 10 MOA chevron inside its guidance circle, so unlike Holosun's own Multi-Reticle sights there is nothing to switch; if you want a selectable circle-dot, that is a different model.

What the HE507C X2 ACSS fits
It bolts to slides cut for the Trijicon RMR and to optics-ready hosts supplied with an RMR-pattern plate. The switchable Multi-Reticle version of the same body is the HE507C X2 green MRS, the newer generation is the HE507C X3, and the same ACSS Vulcan reticle on a narrower slim-slide footprint is the HE507K X2 ACSS.
