Home Forums Hunting & Shooting Savage Collectors Aperture for Marble's automatic flexible joint tang sight

I've got a Savage 99G with a Marble's automatic flexible joint tang sight that is missing the aperture. Does anyone know what the aperture thread size is? I don't NEED the aperture for hunting, but thought one might help me tighten up my groups whilst punching paper.

Brownell's sells new Marbles apertures for the currently-manufactured tang sights that are threaded 10-32, but the sight on my Savage doesn't want to thread in a 10-32 machine screw. Might just be dirt in the sight threads, but thought I'd double-check before I got any more aggressive.

Thanks!

I think the earlier sights use a 10-40 thread. Can't help with finding one, sorry. <img src="/ubbthreads/images/graemlins/frown.gif" alt="" />

Not a bad deal.

Thanks for the link, just what I'm looking for!
