This weather resistant cover will protect the scope in all environments and is soft enough to keep from scratching the scope. Easy modification may be needed for use with backup iron sights. The package will come with 2 different covers. 1 cover is for the scope alone. 1 cover is for the scope while the Weather Shield is in use.
