This instructable will show you how to assemble and operate a G&P WOK Magpul "Desert Storm" Gas Blowback Challenge Kit. You may be able to assemble a different G&P Challenge Kit with these instructions, but some sections may be slightly different. I'm sorry about any pictures of bad quality, my phone's camera wouldn't focus correctly sometimes. Thanks to xplodingplastix on airsoftforum.com for his assembly instructions that helped me in addition to the provided instruction manual (his tutorial was for a slightly different model than the one for which I am making this instructable). Special thanks and shoutout to Evike.com for being such a great company.

Step 1: Materials and Tools
To assemble the kit, you will need:
-the G&P challenge kit (Note that not all parts will be used)
-small mallet/hammer (I used a broken mini Maglite- this will get scratched up if you use one)
-punch tool, or a small metal rod around 3" long
-small steel screw with flat bottom, or metal rod described above
-long nose pliers (you might want two, one that's relatively short, and one that's fairly long and is narrow at the tip)
-screwdriver with a good variety of bits, including philips, flathead, and hex in various sizes.
-metal files (small to medium size, nothing more than 1/2" wide should be necessary)
-sprue cutters/wire cutters
-ink barrel from a ballpoint pen
-scrap of paper (not critical, but helps avoid scratching up the receiver/other parts)
-silicone oil lubricant
-Liquid Wrench lubricant (this is what I used for most of the pins, but the silicone oil works fine too). (I would not use WD-40 for any application in this airsoft gun.)
-clean work area (you don't want to be losing any of the smaller parts)
