Instant magnification toggle: You flip the quick-release lever to jump from reflex sights to 3.35x or 5x power without losing your primary optic’s zero position.
-
Rugged, sealed optics: You get multilayer broadband green glass housed in a solid aluminum alloy body that stands up to 33-foot submersion and fights internal fogging.
-
Precise aiming controls: Tactile knobs let you dial elevation and windage exactly, while the spacious 2.2–2.6-inch eye relief keeps your shooting position comfortable.
-
Quick mounting setup: You secure the scope over 1-inch or MIL-STD-1913 rails using the included height blocks, then attach secondary devices to the forward bracket.
