Open reflex sights usually have one drawback – they are more susceptible to mechanical damage than the enclosed ones. Fortunately, the traditional reflex sight manufacturer Holosun has thought of everything, so you can also buy this custom-made rubber cap for the Holosun HS/HE507COMP optic from us.
When you don't need the reflex sight for shooting, or when you're just transporting your weapon, you no longer have to remove the reflex sight and hide it in a separate case. Just put this cover on it and the risk of damage to the optics will be significantly reduced.
