How to rattle can your PMAG 40 Gen M3

  1. 1. Strip it down

    Take the part off the gun and strip it: pull springs, pins and screws, and take a magazine apart so only the body gets paint (base plate, spring and follower out).

  2. 2. Degrease everything

    Wipe every outside surface with acetone or isopropyl alcohol. Paint will not hold over gun oil.

  3. 3. Mask what moves

    Tape every surface that meets another part: threads, rail slots that take a mount, pin holes, and the inside and feed lips of a magazine so it still feeds and drops free.

  4. 4. Spray the lightest base

    Two light coats of the lightest color, 8 to 12 inches away, 10 minutes apart. Thin coats stop runs.

  5. 5. Lay the pattern

    Hold leaves, netting or a stencil sheet on the gun and spray the next darker color. Work light to dark and finish with black if the design uses it.

  6. 6. Let it cure

    Handle it after an hour but give it a full day before it goes in a case, and a few days before hard use.

Frequently Asked Questions

Can you rattle can a PMAG 40 Gen M3?

Yes, you can spray paint it. Take it apart and paint only the outside of the body, in thin coats. Keep paint off the feed lips, the inside of the body and the follower, so it still feeds and drops free of the magazine well. Polymer takes paint after a light scuff and a degrease.

Should I Cerakote or spray paint my PMAG 40 Gen M3?

Rattle can camo costs about 20 dollars, takes an afternoon and strips off with solvent, but it wears at the edges. Cerakote is baked on by a shop, runs a few hundred dollars and lasts for years. Try both here: the Cerakote colors are in the gun finish paints.

What color should I paint my PMAG 40 Gen M3?

Flat Dark Earth, O.D. Green, Tungsten and Sniper Grey are the most asked for Cerakote colors, and Khaki, Olive and Brown are the rattle can camo standards. Paint them on the photo above to see them on this gun before you buy anything.

How do you get paint off a gun later?

Most aerosol camo paint comes off with acetone or a citrus paint stripper and a nylon brush. Test on a hidden spot first and keep strippers away from polymer parts that the solvent can soften.

Can you paint the barrel and muzzle device?

Standard camo paint burns and smokes on a hot barrel and muzzle device. Use a high heat engine or grill paint there, or leave them black. Suppressors need a coating rated for their temperature.
