Warning: Last items in stock!
These high quality full size flip-up lens caps fit most standard 3-9x40 and 4-12x40 rifle scopes and will protect your scope glass from dirt, moisture, and damage. Clear plastic lenses allow you to view through your rifle scope without opening these lens covers. Includes both front and rear flip-up covers.
Be sure that this set will fit your scope before ordering!
We do not have a complete list of what scopes these caps will fit, so you will have to measure to ensure good fit. Measure the outside diameter of your scope at the objective, and the outside diameter of your scope at the eyepiece.
The front scope cap in this set has an inside measurement of about 47mm, and the rubber will stretch to fit most scopes with 40mm objective lenses.
The rear scope cap in this set has an inside measurement of about 40mm, so it should fit most scopes where the diameter of the eyepiece is larger than 40mm. Scopes with smaller diameter bodies at the eyepiece should use the medium sized caps.
Some force may be required to fully seat these caps, but they are secure once fitted. We have tested these scope caps on 4-12x40 scopes from Vortex and Tasco and found them to be a good fit.
