The Butler Creek 19001 is also known as the Tini Bikini cover. It maintains the same functional characteristics and performance level as the original Bikini, but is specifically designed to cover shorter pistol, shotgun, and red dot scopes. This cover is composed of two flexible, rubber-like cups that are held together by stretch retainers. This design ensures a tight seal that keeps out moisture and dust, providing paramount protection for your valuable optics. It proves to be an indispensable accessory whether your optics are stored away, in transit, or being used in the field.
