At one point, Tech-Sights advertised an acceptable zero shift after reassembly. Now the FAQs say that there is no shift in POA/POI.

I had to tap the pin in and out with a small hammer, but this setup made the SKS hold perfect zero after reassembly.
I got a set for the SKS but I haven't install them yet but I've been more than happy with the 10/22 sights .. B2B
