Grey Man Operations offers initial impressions of the Vector Optics Frenzy Gen 2 red dot sight, a promotional item with Canik SF Combat pistols. Key features include a 3 MOA reticle, multiple brightness settings, and direct mounting to most Canik pistols for co-witnessing. While it performs well and maintains zero, a minor lower glass reflection in low light is noted, though it doesn't impede dot acquisition. The taller window design and manual brightness adjustment are praised.
