Spray paint M4

Hey guys, im planning on spray painting my M4 S System. Im getting kind of sick of the Tan colors on it...(I know what your thinking...why did you get a black version??). I plan to take off the tan pieces, and spray them indivisually. Forgrip and stock is easy. Im not sure about the pistol grip, plz guide me through that one. Should i unscrew it and take it off?

So im curious, which brand of spray paint should i use for it? Can i use the ones that i buy at some arts and craft store? Or should i go online or some airsoft store and order paint for it. Thanks for your help!!!

I recommend reading this thread: http://www.airsoftretreat.com/forums/index.php?topic=35273.0

One of the most all-inclusive airsoft gun painting threads on the internet.

We have had a paint brand thread,,

Anyways, use Krylon Fusion for permanent painting.

Can you buy that kind of paint at a hobby store? (arts and crafts) or u have to buy it at a airsoft store or online?

You can get it at Walmart .
