I've been waiting since Feb 7th.
I needed the plastic cover for the optic cut out on my 2.0 10mm because it was such a *** I wanted to trade it in, and I had lost the cover.
I tried looking into the aftermarket but no one sells any covers for the 2.0 slides.
They sent me a mounting plate instead two times in a row over the last few months after I had thoroughly explained to them several times that is not what I needed, and I am still waiting for the plastic cover, even though the 10mm is long gone because I just said screw it and traded it anyway without the cover plate.
