Monstrum Pro Series Flip-Up Scope Lens Covers

Monstrum Pro Series Scope Lens Covers help you keep your glass clean and damage free for when you need it most. Rubberized sleeves are crafted from an improved rubber formulation - designed to fit snug around your scope tube with more resiliency than ever before. Spring loaded flip-up lens caps deploy with the flick of a thumb and secure tightly when not in use. Each package includes one Flip-Up Lens Cover. For optimum fit, carefully measure the diameter of both your rifle scope's eyepiece diameter and objective lens diameter and choose the size from the chart below. Example: if your eyepiece measures 31mm, then you should order Size C so it fits tighter.
