Had this mod once and decided it was very busy, but I really liked the sniper rifle. There's only one mod (sniper rifle revived something) that adds one that I've seen. Is it possible to just have that or can someone tell me the best way to essentially "extract" it?

nvm I managed to do it, don't know what the rules are for posting edited mods so maybe if someone else cares enough for it

If you go back to the main page, and click on the 'license' line, it will tell you what license the mod is posted under.
THIS mod is posted under Bob's mods copyright, which FORBIDS modified copies. So you're violating it with your standalone.
Plus, from a glance, you're actually not disabling most of the other features.

Both the sniper rifle and sniper rifle revived mods are posted unlicensed, so you can use them as a base without issues.
