Can't find a certain gun mod

[The Real Right Shark]

I'm currently trying to trick out my Gatling Laser, but I can't find the Gatling Laser Focus Optics. I looked at the wiki, but the only 2 places that it is sold at, they aren't there. I never bought it, and I tried waiting 7 days for a restock and still nothing. Anybody know what's going on?

Restocks are every 3 days, not 7, and what's sold is entirely random outside of certain items like Sprtel-Wood at the Silver Rush. It's literally just a wait-and-see until you find it.

Yeah its pretty much dumb luck especially early on when you don't have caps to just buy new mods when you see them.

Honestly though it seems really stupid of the gun runners to not offer some sort of specialty order program at their kiosk where you pay more but have access to their full stock of mods.

There's http://www.nexusmods.com/newvegas/mods/41267/? if you're boring and not using any other weapon mod mods, or http://www.nexusmods.com/newvegas/mods/47712/? if you're using WMX and don't mind waiting a bit...as was already stated, that's a non-issue.
