Basically it's a full arsenal with no ammunition (you have to acquire your own) of BB Gun.

Not sure if it collides with anything, but it all can be found in the El Dorado Gas and Service.

These small lever action weapons of minor destruction have been somewhat tinkered with so they don't act too over or under powered to the rest of the base weapons.

All ammunition types should be vanilla, although the Mini Nuke version may be using the GRA ammo list.
