So got to the range to shoot the CORE with the FF3 on it, and got it sighted in fairly quickly, but after about 3 mags I couldn't see the dot through the center anymore, only around the edges. The lens looks fine but it appears that maybe a casing flew back and crack the glass. Kind of disappointed.
Wasn't really paying attention to how it was throwing cases. Will have to go back soon and see where its ejecting cases at.
