While toying with the idea of getting some work done on my g19 I discovered the gen5 MOS. I had planned on getting front serrations and considered milling for an optic. The new MOS solves both those wants from the factory. My current gen5 has Glock night sights and the factory extended slide release and I have installed a rainier arms MARS. But will prob keep the M.A.R.S. for the next one. I would really like to step into the MOS for under a $100 if I sell this one but wasn’t really sure how much would be a reasonable asking price. I don’t keep up with round counts but I’ve taken a class with @apachesolutions and had some 1on1 time there. So I would say around 1k rounds through it by now. Lemme know what you all think $550 too much? Pretty sure they still run $599+ new.
