My experience: Just recently (4 weeks ago) sent in a Ruger Precision Rifle in 338 Lapua for repairs (handguard came loose). Talked to a very pleasant individual, that only asked for the serial number and address, then sent me a shipping label.
Sent rifle to them next day, receivedan email 2 days later that they'd received it. Two days later another email that it had been assigned to a service tech, and 2 days later they again emailed to let me know it was on its way back, what they had replaced and why, that it had been test fired and cleaned. Two days later received repaired rifle with new parts installed, a test target with 5 shot group, and explanation of work done. For the heck of it I ran a patch through it: it HAD been cleaned!. Took to range and fired: everything good.
Now for the opposite experience:
In the last year I've had to send back a rifle to a High End manufacturer for repairs twice (they claim a Lifetime warranty on their stuff) because fired ammo exhibited high pressure signs (6.5 Creedmore). The tech I was transferred to upon calling sounded extremely put out with my problem, and told me that the ammo I was using (Hornady ELDM) was known for blown primers due to soft brass, and to switch ammo. I countered with my also having the same problem with Berger Match and Federal match, and this "Tech" proceeds to tell me they also had soft brass. I lost my temper a little bit, and he finally sent me a return label and number .
Got a note 4 weeks later telling me the rifle was on its way back: no other explanation given. Received rifle back, no repair note, so I called the manufacturer, and was transferred to another "tech", who looked up the paperwork and said they had run a reamer through the chamber because it was "a little tight" . I asked why it took 4 weeks to "run a reamer in the chamber" and was told most of the "team" had been at Camp Perry the last 2 weeks for the National Matches display and support.
Fired "repaired rifle: same problem with aforemantioned ammo (Berger, Hornady, Federal), plus this time the groups had gone from a very nice 3/4" to over 2". For reference: they guarantee 1 MOA on most of their rifles.
Called them back, got the same rude tech. This time he didn't argue, just said "Ok" and sent the shipping label. 4 weeks later I get the rifle back: no emails, no calls, no information. I fired rifle and groups DID shrink to 1 MOA, but high pressure signs and blown primers were still there. I took a huge loss on that rifle and sold it to someone that said they'd try to fix it. Will never buy another gun from that manufacturer.
So, that's my experience with Ruger versus another company selling similar gear, for about twice the price.
You decide.
