Not a word came back with mine. Wouldn't have even known it was on its way back if I wouldn't have called and asked. When I called they told me it was shipped and gave me a tracking number. When I checked the tracking number with Fed Ex the rifle was already within a day of my house.
No they did not on my 15-22. As a matter of fact, I called and asked them what they did and they did not know. CS rep said that the gunsmith puts notes and if he doesnt they dont know anything, which they didnt.
When they sent mine back I had a letter stating what they did. 1 update to latest spec.2 replace/repair springs 3. replace all magazines. pretty cut and dry
