No sealing plate - Trijicon RMR Type 2 1x 1 MOA Adjustable LED Reflex Sight

While so far I am very pleased with this red dot, I want to take the time to note something for other prospective buyers. Even though this is a premium price, be warned that it does not come with a sealing plate. (A thin piece of metal that helps keep water out of the unit that sits between the red dot and gun) That is a separate $15 and more days of waiting if you didn't buy it at the same time like me. I just hope in the future that for the price of this unit, they can throw the sealing plate in too.
