MONSTRUM OPTIMUS 1X PRISM SCOPE BLACK PT1B-BDCP4

The Monstrum Optimus 1x Prism Scope is a prism scope optic featuring a true 1x sight picture, an improved eye box over previous generation Monstrum prism scopes, and a generous eye relief of 4.5+ inches.

It offers similar functionality to red dot sights for rapid short range target acquisition, allowing for both eyes open targeting. But it uses a glass prism optical system with an illuminated etched reticle instead of the light projected dots used in red dot sights.
