Mount this to a rifle with a scope to have a backup close quarters sight. A normal rifle sight like the Swampfox Liberator green dot or an LPVO will mount on top. You can mount this Kingslayer at a 45 degree offset as a backup for fast sight picture acquisition.
The Kingslayer is a super compact, highly accurate micro reflex open red dot sight featuring three bright reticle options that allows for fast target acquisition with both eyes open while focusing through to the target. It is an RMR-compatible footprint for reciprocating pistol slides . For rifle or shotgun platforms, Kingslayer comes with a low profile 1913 Mil-Std Picatinny mount already installed. Kingslayer is waterproof, fog resistant and features a scratch resistant, silver lens coating, which is also anti-glare. Built like a tank, Kingslayer can withstand 800 g’s of impact and maintain zero come what may.
