OK so my friend bought an Echo 1 Scar light froom parafrog in knoxville last year and everythings been great till now. I sorta kinda....broke his stock...maybe. well ya know that button that you press to fold the stock? when i opened it up it jumped out at me and a spring did too. I didnt know if the spring went first or not cuz it happened so fast so i put the button back in first and now we cant get it out and the stock wont catch to the rest of the gun cuz the spring isnt behind it. Does anyone know how to get that button out? We have tried the manual with no luck.replies will be appreciated, thanks.
