I haven't yet figured out how to repair weapons (heck I haven't even figured out how to check whether they're damaged...) but do we use components of an identical gun to repair the one you have? Like NV and FO3 we used to click R in the pipboy and repair?

Can someone help me on how this works or direct me to a site which explains (the wiki is empty of info for now).

I don't believe durability plays a part in Fallout 4. Only seems to apply to your Power Armor suit.

Yep. Your guns won't get damaged.

Yeah, I was surprised that our weapons don't degrade any more. Nevertheless, I wonder in the early going if there's any point to keeping duplicate weapons....

Weapon durability was removed.

You mean only the power armor gets degraded?

Not even other armor or items of clothing?

The only reasons to pick up duplicates are to scrap them for crafting components or to sell them.

Pretty much. Repair and durability for all armor and weapons is no longer a thing. So no point in carrying duplicates of weapons/armors unless you want to sell or scrap them.

Don't keep them. Sell high price weapons scrap low value weapons. Get the perk that give you springs/screws it will help.
