As Toomany said, the RAR does have a couple hunks of pot metal (zinc aka zamac#3) in the stock. I'm not a fan of zinc in any firearm and I believe its only redeeming quality is that it is cheap. However, I really do like my RAR.
I'd like to buy a nice walnut stock for it. Why don't I just purchase a 77/22, you might ask. I'd like one of those, too, but the RAR has a 60-degree bolt lift and I believe the 77/22 is 90-degrees. I've come to prefer the 60-degree lift.
If Ruger wanted to save some money, they could eliminate the dovetail in the receiver for scope mounting. Their receivers are also drilled and tapped for scope bases, which I prefer over dovetail grooves.
As far as accuracy goes, the barrels are probably produced on the same equipment for both models (10-22 & RAR) and it is a toss-up as to which one will be better on any given day. Ruger very likely pulls rifles off the assembly line every shift for accuracy testing as part of their QC and I'll bet their accumulated accuracy data overlaps one another.
At the risk of being reprimanded for self-promotion here, I am the DauntlessEndeavors guy and I thank you for the kind compliments.
Lately, I've gone down the 22 bolt action rifle rabbit hole and currently own 6 different brands. I keep testing them back and forth, trying to decide which ones I like the best. I can say right now that if I were to get rid of three, the RAR would remain. Even after setting back and rechambering the barrel, it isn't as accurate as the Tikka but has over 2000 rounds through it and has been 100% reliable. One of my mantras is that discussions of accuracy are all well and good,,,as long as the rifle is reliable. If it isn't reliable, well, accuracy really isn't as important then.
