This is a transparent lens cover made from durable rubber with a snap closure and flip-up function. The cover flips open easily and stays securely in the upright position until it’s manually closed again, sealing tightly with a small click.
The lens cover is mounted on the scope by sliding it over the rear end until it locks into a groove on the scope housing. With this type of cover, which remains attached at all times, the lenses are protected from scratches, dust, and debris during use, transport, and storage.
The transparent flip-up design allows you to see through and use the scope even when the covers are closed.
