anyone in San Diego have an AR or parts?

I recently got a Jager ap74. It is a 32 caliber ar15 clone. I was able to make it fire easily enough. Now I am trying to make it cycle reliably. I've done all I can with cleaning and lubing and got it up to 90% reliability. I think I've narrowed the cause down to the action/buffer spring, and there in lies the problem. They haven't made this gun for over 20 years, and parts are rare, if not impossible to find. I was hoping to find someone with an AR who would let me borrow an action spring to test for both fitment and function. Many thanks in advance for any help, Chris.
