How do u fix the stock on a Crosmen r76 airsoft gun?

You can start by going back through all of your answers in the hunting section and deleting every one of them where you lied. Like the one where you claim you saw a guy bend a AK barrel with a base ball bat and the gun still worked. Anyone with more than 10 minutes of real firearms experience knows you lied. A gun with a bent barrel WILL EXPLODE, a bullet will not travel around the curve of a bent barrel without producing excessive pressure and exploding the barrel and action. No one likes a liar, not even your parents.

you can throw it away or give us more details about what is not working.
