Sunguard ARDs are designed to fit inside Butler Creek and Quake flip covers.
Check the size chart and installation instructions below to find a ARD fit.
Gently push the SunGuard ARD into your scope cover until the front of the disk is seated against the inner ring of the cover, then press cover onto your scope. With Butler Creek covers, the small end of the ARD faces forward; with Quake covers, the large end of the ARD faces forward.
The thin plastic ring is to be used ONLY if the SunGuard® ARD falls into the front of your scope (a few rifle scopes have an edge around the objective lens that is too thin to support the ARD). Place the ring between the ARD and the front of the scope:
Treat this SunGuard ARD with the same care you would any fine optic. If the honeycomb becomes dirty, remove from scope, rinse in clear water and then blow dry.
