so I ordered some CMMG magazines for a .22LR AR platform and while they function great, they are battleship grey. Now, there is nothing wrong with battleship grey as a color, just not on a black rifle. So after seeing how people were using Rit Dye on wood furniture, I figured I'd give it a shot on plastic.

Disassembled the magazines, since I didn't want to dye the follower, and soaked them in black RIT, and after an hour they came out as if they were molded in black plastic, they look factory. I can't recommend this more if you are looking to change a magazine's color (assuming your mag is of a light color)

Procedure I used is:

1. Disassemble and clean mag bodies with soap and water, and rinse thoroughly.

2. Add 8 OZ bottle of dye to about 6 quarts of water and stir (don't use a pot that you use for cooking, I got a cheap stainless steel pot at walmart for 5 bucks)

3. Heat the dye and water mixture to really hot (150-180) heat will slightly expand the plastic, allowing the dye to really penetrate (heh, penetrate)

4. Add the parts to be dyed, shut off the stove, and let it be for about an hour, and stir it up every 15 minutes or so.

5. Remove parts from pot, rinse and let dry.

6. Reassemble and enjoy.

Equipment required:

sacrificial pot. I got one from walmart for 5 bucks (not sure if it's safe to eat out of it after having dye in it like that
RIT liquid dye. Costs about 3 dollars for the 8 Oz bottle
Stove or other heat source
Tongs to fish out the parts. (it will stain your skin if you reach into the pot)
