Been using R77s for 40 years with no gun failures.
I have over a dozen covering multiple models.
First was a 77 in 270, second a 77RL in 308. They are my "go to" guns.
Also 77s in 284 Win, 44 mag and 22 mag.
I have had little reason to deal with Ruger, but when I did they were curtious and help full.
Most of this was for 10/22 parts with springs, sights, screws, etc coming free to me.
Nephew just had a Red Label reworked by their service department. Returned in in near new condition--free.
Replaced metal parts, fore end wood, etc Hard to beat this service.
