Glass Reinforced Nylon scope protector to protect the lens in your zoom scope. The BB protector is virtually indestructible from plastic BB impact (tested with a 3.2J sniper from 2 feet), and the hexagons are sized so BB's are not able to enter.
This scope protector fits perfectly the between the Vortex Crossfire II 3-9x40MM Scope's original flip up lens protector and the scope's objective lens cowling.
Aside from a very slight decrease in light, the protector is invisible when looking down the scope!
For other scopes, measure the the inside diameter of your flip up scope protector with a caliper, the listed diameter is the Outer Diameter of the protector, attach between the flip up lens protector and the scope. This protector requires a lens protector to be secured, alternatively, you can black electrical tape to the front of the scope. It's recommend to get a protector equal or slightly less than your scope's objective lens' outer housing diameter to ensure it fits inside the flip up lens cap.
22mm to 52mm sizes available!
