Nf optics ready night sights - Night Fision Glock Tritium Stealth Yellow Front/Square Night Sight Set

installed on a 19.5 RMR direct cut slide. I have an RMR type 2 RM06 mounted + sealing plate too. With this combo. Rear tritium is slightly above the back of the RMR base. Front blade is not absolute co-witness but also not lower 1/3rd? I have vision issues and blacked out sights are not an effective BUIS system for me. While I understand some may find the dots distracting\busy, contrasting front post (yellow) work for my usage. Easy to install with the proper tools and appear to have not come loose or shifted during the 100+ rounds i put through the slide so far.
