Very nice used official HK sight bought from HKparts. Net, not a cheap imitation. It’s darker black in person, pictures make it look faded. Also have matching rear diopter sight for sale. Not sure how to measure it, I’m pretty sure it’s the 28mm version that is made for the rear diopter sight. Rare hard to find, always out of stock. See pictures, I can provide more measurements upon request.
