There seems to be quite a bit of confusion about where to find these Rainbow rarity items. Contrary to popular belief, Haderax does not drop every Rainbow item. Different slots are tied to doing different things in the DLC. Since there are more than one of everything (but not many), I’ll list all of them, but I will highlight what I felt were the easier items to farm by putting asterisks next to them like this**. You only need to find one gun if you have someone to help you dupe it to make 4 of them. Simply have a rainbow item equipped in every slot (except class mod) at once to unlock the achievement. This can also be done on any playthrough.

Please take caution that there will be story spoilers in this guide.

Guns

Toothpick (Assault Rifle)**: The best way to get this gun is by doing the side quest The Hunt is Vaughn, Vaughn’s second side quest (you have complete the first one he gives you with the bandit flags). This will take you to The Burrows where you have to kill worms. Simply keep killing them (don’t pick up the trophies that drop), and this will eventually drop. If it doesn’t, simply quit the game and reload. You’ll spawn only a few feet away from the worms (A Batwoman has stated in the comments that you can return here after the quest and kill the worms for it). NOTES: The Retainer shield can also drop here. This gun has the highest drop rate of the Rainbow guns.

Infection Cleaner (SMG): This has a chance to drop off of the enemies known as New Pandora Infectiologist. Unfortunately, theres not a lot of them, and it has a low drop rate.

Peak Opener (Torgue Assault Rifle): Has a chance to drop from the Haderax chests, like the Easy Mode shield. Thanks to CodeMonkeysGuy for telling me about this one!

Nirvana (SMG): “dropped from a badass when I was getting the samples in the Spore Chore quest right at the start”. Thanks to Calex dEUS for this find.

World Burner (Rocket Launcher): “from Bricks quest "BFFFs" drops from killing a Lt. in Dahl Abandon only appears after doing the flags for Vaughn”. Credit goes to A Batwoman for this find. Please note that this possibly only drops after doing the story missions for this DLC.

Hot Mama (Sniper Rifle): “drops from Lt Hoffman in Mt. Scarab.“ Credit goes to ikilledbecka.

Unicornsplosion (Shotgun): After doing the side quest ‘My Brittle Pony’ and saving Buttstallion, she’ll go to The Backburner. Go there and feed her eridium while having the Mysterious Amulet equipped (you get the Mysterious Amulet from the Tiny Tina’s Assault on Dragon Keep DLC). Note that this is a random drop from Buttstallion.

Shields

Retainer**: See above on the Toothpick section.

Easy Mode: This appears off of Haderax, the raid boss. Check the chests for a chance to get it.

Note: from what I saw, both of the shields have a fairly high drop rate. Farming for either is fine, but maybe killing the worms in the Burrows might be easier for some since you don’t have to fight Haderax.

Relics

Mouthwash**: This is given to you by Lilith as a quest reward at the end of the DLC, when you return to The Backburner after defeating Hector.

Hard Carry: Has a chance to be in the chests after defeating Haderax. Seeing as you’re gonna get a free one for doing the story anyway, it’s not that big of a deal. (Thanks to IllegallySam for contributing the name of the relic).

Grenades

The Electric Chair: Has a chance drop from Uranus. (wink) Story related boss. You can return here to fight him again after you beat the story. Simply quit out after killing him if it doesn’t drop and you’ll spawn back into the area. Just gotta run back to the boss.

Antifection: Has a chance to drop from Cassius. Story related boss. You can return here to fight him again after you beat the story. Simply quit out after killing him if it doesn’t drop and you’ll spawn back into the area. Just gotta run back to the boss.

Notes: In my experience, Electric Chair has a higher chance to drop, but the grenades seem the rarest to me. This one could go either way, so just go for whichever you prefer.
