Si creates garbage and doesn't stand by their warranty - Strike Industries Glock Gen 3 Liteslide

I recently purchased a Liteslide for gen3 G17. Upon building the slide I attempted to mount a brand new Holosun 509T with a C&H RMR adapter plate. I quickly noticed that the optic was skewed so far that I had to max out windage just to get the dot centered in the window. I also tried with the plate supplied by Holosun as well as with a Holosun 407C and a Swampfox Liberty. All mounted crooked.

I contacted Strike Industries for a Warranty RMA explaining what the problem was and the rep asked for multiple photos which I provided. I also provided detailed measurements taken with a dial indicator which clearly shows the RMR hole pattern was off.

Before closing my RMA tocket, Strike industries reply was "The Liteslide may not be compatible with aftermarket mounting plates" and completely ignored the fact that I used two other optics with the same result.
