I believe the brass posts are the same length on the Gen 1 and Gen 2 fixed scopes. And while they are definitely longer than the 3-9, you can still put a shorter cap on them. I will often take my windage caps off when I’m hunting and replace with the cap off a folding chair leg.See my reply above it’s the brass post on the scope itself that is tall on the Gen 1 fixed scopes. They aren’t getting shorter with only a cap change.
