I just received my T-36 back from Weaver repair. It was a two year old scope and I could not find the sales receipt, I called the Weaver repair folks and they said not to concern myself about it, they gave me a return authorization number to use when I sent it in.
Since it only came back yesterday I have not had a chance to try it but it did contain a repair checklist showing what was repaired on it and it was all at no charge, no hassle. It took just about a month from the time I sent it in until it came back - good enough service for me.

p.s. - the Weaver website has the phone number and full instructions for getting the return authorization number before returning the scope for repair.
