If you had to mount a scope on a grooved .22 receiver...

[Chris in TN]

Given this board's focus on reliable scope mounting, what's the consensus if you need to attach a scope to an older .22lr with a grooved reciever designed for 'tip off' mounts, and you want it to hold zero?

Let's assume having it drilled and tapped is a bit excessive and might not even be possible and stick with options that utilize the existing grooves. Either a pic rail adapter and a set of rings for that, or a set of rings that go right on the grooves.

I've also considered using a plain set of rings but adding a third ring (by buying two sets of identical rings) or even a fourth if it would fit.

What say ye?

I realize there's likely no perfect solution here. Just looking for 'functional within reasonable limits'.

I’ve used Sportsmatch rings on CZ’s.

If I’m understanding the question correctly.

I use a DIP rail on all my CZs. I am fairly sure I have an extra one if you need one.

Multiples of those as well with no issues.

It's a 22. How hard are you using it?

I can't say that I've had an issue with a scope on a 22 moving, even with cheap dovetail rings

I appreciate the offer but I'm not sure that would do it - the CZ rail is a hair wider, as I understand it, than a standard 3/8" groove like American makers used to use.

But you saying that reminded me that I have such a rail myself - a Triggers by Scar rail I used to have one one of our CZs - and it's *slightly* wide. I think it would tighten down with the set screws, but I'm not sure it's tight enough to trust.

I’m also using a DIP rail on a 22 Mag with a 3-9x40. No issues with my setup.

It's not 'how hard', it's 'how often'.

This is for my old Mossberg 144LSA. For ~12 years now it has been an almost constant companion. We live on a more-or-less working farm with a peach orchard and cows, goats, pigs, and chickens, not to mention wildlife. Every time I leave the yard some firearm goes with me - sometimes that's a .22lr, sometimes it's a single shot shotgun. Today it was an AR I had checked zero on before going to 'work'. Didn't want to walk back in the house to swap. I spent several hours trimming fruit trees and cutting next year's firewood.

But the point is, that rifle gets hauled around several times per week, almost all year, and a lot of that is on either a SxS gun rack mounted up high (meaning it rattles and vibrates a ton) or on a 4-wheeler gun rack mounted on the front rack. So it gets bumped a lot. And it'll go squirrel hunting a couple dozen times every winter, and I use it running traps.

Anyway, several days ago I rezeroed (switching ammo - which I'd never do if CCI #056 was always in stock when I run low) and I noticed the rings had slid forward a bit. Either that or I had an attack of stupids when I mounted the scope. The current scope has been on it maybe 4 years and I don't remember if I swapped rings when I swapped that scope. Or if I even gave a conscious thought to the rings at all. I just know they were further forward than they should have been - the front one, wasn't even fully on the groove anymore, and the back one was edged into the ejection port gap in the rail.

The rings (I can't identify them by just looking at them and can't find an invoice when I bought new ones, I assume they're the ones that were on it when I bought it) are *probably* ok. I just moved them tonight, tightened them properly, dabbed some blue threadlocker on them, and will rezero (since I moved the rings) tomorrow.
