anyone ever had a bad ruger ring?

[Lloyd Smale]

took out a 257 roberts i picked up a short while ago and mounted a 2x7 leupold that had previously been on a couple other rifles with no problems. Got to the range and with the scope adjusted all the way to the right with the adjustments topped out the poa was still 3 inches to the left of the bull at a 100 yards. I thought maybe the scope took a crap so i took the gun back home and grabbed a tasco world class out of the junk box and put it on and had the same trouble. First though was the dovetails were machined crooked but i check it out and they seemed to be right. then i pulled the tasco back off and a light bulb lit. I took the front ring off first and when i did the scoped popped and and torqued to the side. I went back to the junk box and found a differnt rear ring and it cured the problem total. In all the years ive had rugers and ive had many ive seen about every problem imaginable with one but never a ring drilled off center. I wonder if thats why it was sitting at the gunshop.

I've never had a bad ring. I have experience with probably a hundred ruger rifles. I have seen one M77 in .25-06 that had the dovetails in the reciever out of spec.

I have, however, seen problems with the rings when mounting them to the receiver. It's fairly easy to get them off-kilter when tightening them in the dovetails.

I got a set once that would not fit around a scope or a 1" steel lapping rod. Well they would it I tapped them on with a hammer. I did this on the bar not the scope. Once on the bar I figured i could lap them and get them to fit. Well there was so much gap I could not get the screws to reach the bottom half of the ring. Ruger sent me a new set. So after seeing that I think anything is possible.

Yes..........And a bad receiver on A 77/22 And, remember, the rings are each a matched set and have to be reassembled as originally built; one must absolutely pay attention to the matching of ring's top and bottom halves. - - 8)

While selling guns for a few I have seen many people not install the ring properly onto the receiver. I too have seen that the rings seem to be machined in such a way that they are not interchangeable. There has to be a logical reason for this in regard to manufacturing, cost, time, etc. Otherwise I feel that it is lame. If they are in fact this way ruger should mark them in order to insure proper installation.

To the OP: As mcknight77 said, check to make sure that the rings are centered on the receiver correctly. Take the rings off the gun and take them apart and note how the half moon is designed on the lower ring/base screw. It is made line up with the scallop on the receiver. When putting the ring on make sure that the parts align correctly by seating the screw end with the half moon into the scallop on the receiver and then while holding in the correct position tighten the other side to insure that it is lined up correctly. It does not take much misalignment at the receiver to make huge differences in POI. If you have it put together wrong and you just took off the top screws to change scopes then that would explain why the Tasco had the same issue. I apologize in advance if you have it right and I'm just yapping. If that is the case call Ruger and they will take care of you. Good luck and update this post when you get it figured out.

I had the same issue with a #1B 257 Roberts I just got. It was the first time I ever mounted a scope on a Ruger. Seemed so simple I was probably not as careful as I should have been. The front ring wasn't lined up with the "notch" on the rib. After I figured it out I loosened the screws and got things in proper position and tightened them down and it was perfect.

It's real easy to get in a "hurry" when doing a simple scope mounting job. "Been there,Done that" a few times! As noted above, any slight miss-alignment with a ring, base or screw can make you start wondering what you did "wrong" when everything looks "right". After all these years, I now take my time when mounting scopes. Good troubleshooting technique to "try" another scope when in doubt..................Dick :!:
