I have a old CVA hawken that I got as a kit gun in the 80's, I have been using it since then, about 5or 6 years ago the trigger assy broke, I contacted them and they had ne ship it to them, they returned it in better shape then new.
I was real impressed with their customer service.
I would call ,e-mail, and write the company and being very polite tell them the problem and tell them the solution you want.
Keep at it and you will eventually get results, a lot like Turkey Hunting
