Water Resistance: IPX-7 Shockproof/Fogproof: Yes Ok, so the Bravo 3 is feature-laden. Not unexpected considering Sig’s pedigree. The first thing that really jumped out at me is the “Megaview” feature of a 10° viewing angle. The Bravo 3 does have a generous view field, further enhanced by an excellent lens design that seems to make the black “rim” around the view field nearly disappear. Some other prismatic low magnification optics tested recently seem to have a large dead zone around the view box. The Bravo 3 is edge-to-edge clean, which reduces the tendency of the shooter to focus through the optic at the expense of wider situational awareness.
