Needs mod but works great - Holosun 407/507K Sight Mount MOS Adapter

I had a really hard time finding a way to mount my hs407k on my G47 MOS, and this finally did it. The only issue is that, out of box, it doesn't fit the MOS mount. I suspect the tolerances were calculated without the coating, and once it was applied it no longer fit. I spent 5 minutes filing off one side of the coating and it fit perfect, no issues otherwise. So I recommend the product, but keep in mind you might have to do a small mod
