Hey,

I can't figure this one out.

I bought some Weaver Quad Lock rings (#49046) and the rear ring is kind of loose on the Ruger supplied base.

I have read others noticed the same thing.

Is it the ring(s) or is it the base? I couldn't find a conclusion to this, just that it happens on occasion.

In other words, should I buy a new base or try some other rings?

Thanks

Agree, I had to replace the factory base with the two part Weaver base, works great! Had the same problem, rear ring clamp wouldn't tighten up.

Bought a set of Weavers a couple months ago, same problem on Ruger base and they still didn't work on a couple of picatinny rails either, figure the rings are not to spec.

I believe the problem was with the Ruger base. The rear slot was just a bit to wide I think

So I retired the Ruger suppled base today and replaced it with the Weaver TO-9 (48201) and some Weaver quick release tip off rings (49192). The 49192 may be a "made for Walmart" product by Weaver. It doesn't show up in the Weaver website data base.

No matter. Total cost for the base and rings was around $14.

The scope seems to fit very snugly now. We'll see how it does tomorrow. I'm particularly interested to see what happens with zero after takedown and after takedown with the quick release rings removed and put back on.

I'll let you guys know.

Funny ... I just ran into the same situation a few days ago when I was mounting a new scope on my 10/22 TD. When I tightened the cross screws, the Weaver Quad-Lock rings were still loose. I solved the problem by driving the cross screw out then grinding off about .030" from the area where the clip catches the ring body. I used a belt sander to remove the metal but I'm sure a file would also work. When I put the cross screw back in, the ring would fully tighten. I didn't check to see if the Ruger scope base was too narrow or if the ring base was too wide. Anyway ... the Quad-Lock rings are now tight so I guess it really doesn't matter. I have used other rings on the Ruger base with no problem so I assumed the rings were defective. The area I ground is not visible after the clip is replaced.
