How to remove the sticky-gunkey-ugly glue on recievers!
In 10 Easy steps!

First Steps
1) Get $2 and enough change for tax in your given location.
2) Take a drive to your local True Value, Dollar Store, Drug store, etc.
3) Get out of the vehicle and enter the building.

Now... for the important part.
4) Find Ronson Lighter fluid. Not sure if other brands work. I amagine they may.
5) Pay for Ronson Lighter fluid. (It's a yellow squeeze bottle with a blue top)
6) Drive home in your vehicle of choice, your own is recomended.

Once at home...
7) Take out your metal bodied M4/M16 series rifle.
8) Find a cloth. (May be substituted with your wife's favorite underwear - that you hate)
9) Squirt a small amount of fluid onto the gunky glue area...

The final step!
10) Wipe fluid from reciever and drool over your gun.

...and if you really want, the Stupid step!
11) Strike match and hold to reciver, best effect if done before wiping fluid from reciever.

Warning!
Do not use lighter fluid cloth to clean your drool. It is poisonous.
Do not use lighter fluid as either a) a sexual lubericant, or b) a Airsoft lubericant
I am not liable for any damages done by taking the 11th step. I am in no way suggesting this step.
Be sure to film and post this step if taken.
