Element Protective Lens Cover for Eotech 551 552 553 Dot Sight
Fits nicely over the 552 I also bought here. It however does get ur field of vision wavy and blurred looking through the darn thing. I compensate by always looking through it with both eyes open which should be the case anyway for better "situational awareness". Small price to pay for the protection it provides.
