Sorry if this is a dumb topic, but I'm just looking for really small mods to add to my game. Just things that add one or two pieces of armor or a couple weapons. Any recommendations?

Fallout Nexu... All you need to know.

While you have been told where to look you were not given any suggestions so I'll give out a few of my faves. For the record I'm no modder and I have no affiliation to any of the authors other than I downloaded and used their gear. I reccommend any of Slam53's weapon packs (Sniper Pack, M16 pack, MP5 pack, M4 pack, tactical Desert Eagle) They are not just left out somewhere you actually have to work to get them. The sniper pack is in the National Guard Armory. Daejones did some good power armor (Colossus Tesla was my choice.), Dragonskin Tactical Outfits are very popular also. Hope I was at least somewhat helpful.
