Hi DeMoNeye, welcome to the Forum. Don't go buying a whole new gun just yet cos I bet a pound to a penny that either someone here will point you in the right direction or you'll find something in the for sale sections. Have a look at the forum rules as you'll need to make a few posts/join threads before you get to see the 'For Sales'. It won't take long. Try starting in General Airgun section and see if anyone knows where you might get a stock from
All the Best
Paul
