I got a bronze battle pack and opened it from my loadout in battlelog. Inside it was a green laser sight and a couple of other things. Now I look at all the guns I have, and there isn't an option to put a green laser on any of them, the option is greyed out like i haven't unlocked it yet.
How does this work?

I don't think they work in this. The way they work is that you recieve one and inside is a random assortment of attachments, camos, knives or dogtags. But in this build, i don't think Dice have allowed us to select any of the contents.
In the beta, you unlock stuff by getting kills. But then you unlock alternate 'types' by battlepacks.
ex, you can get a red dot with 10 kills, but the Coyote Dot is in a Battlepack. The difference is *mostly* cosmetic - the Coyote dot is less obstructive and smaller.
I think that camo is also in Battlepacks.
Battlepacks contain random goodies that are rated with "Rarities." Think of them like booster packs for trading cards. Or, alternatively, if you played Mass Effect 3, it's identical to how that game worked... except you don't "buy" Battlepacks, you earn them. Although I bet there will be a way to buy them in the final game, hopefully with in-game points. There has to be a way to continue getting them once you reach max level ... otherwise the backlash will be enormous.
