Not sure, but a Vortex Sparc2, regarded as pretty tough, lost zero on my Air King after maybe a couple hundred shots. Don’t know if it’s broke or just couldn’t hold on. Might want to ask Burris first. They do use them on auto pistol slides, so maybe it’ll take it.
I replaced it with a SWFA 6X, springer-rated.
