Thanks, jbotto. There are a couple of tapped holes in the barrel. They are just hidden under the objective lens of the scope.
While we're talking about sights, I'm considering the XS aperture, which is embedded in a Weaver-style mount. It's 65 bucks but it'd probably save you that much in ammo over the years. The only time you see it is when the scope comes off and there it is, all zeroed and ready to use. Just set it and forget it.
