Sure it's a option, if your running a globe front shooting HP you will have a globe mounted in a iris as a optional iris..
I'm old school HP, I don't believe I have seen a M1 or a M14-M1a on the line with a globe front sight... I am sure there might be a few out there.. But certainly not mainstream.
I have seen AR's with Medesha front sight bases with a bubble, and a few others buy I really have not been looking for them either.
I think you see more on bolt guns in HP than other rifles..
I don't believe I have ever seen a set of Redfield Palma's or International sights that came with a bubble in the front globe either.
Tag you're it...

There's a reason I specified in capital letters Match Rifle and not Service Rifle, by definition a Service Rifle cannot have a globe front sight. Gehman, Phoenix, Centra, Right Sight, Medesha all offer front globes with levels.
