Center Fire Scope On A 22LR
I have a fixed 4 power scope for a 5.56 rifle that I'd like to use on a 22LR Rifle.
Being a low power scope, will I have a problem with parallax?
I'm not going to be using it for target shooting, just yard critters.

I don't see why. The only real difference between centerfire and .22LR/air rifle scopes is how robust they are.

You'll never get the top accuracy without a parallax adjustable scope, but I don't think the parallax would be an issue for shooting the average yard pest. The animal great beyond is full of millions of varmints that have been killed with fixed parallax centerfire scopes mounted of rimfire rifles.

Often the fixed objective rimfire scope are set to be parallax free at closer yardage than centerfire scopes.

I have an air rifle with an incredible centerfire scope on it. Shoots .177 pellets with deadly accuracy. I can't tell you how I know this.....

Mount the scope on the 22 LR and when sighting keep Your head - eye and target centered in the scope and it should work fine .
Parallax only shows itself when you move your head-eye around to the outer edges ... just keep head-eye centered and it should be Okay !
I consider a fixed 4X scope a pretty dang good choice ...
... Roll with it !

Most rimfire scopes have the parallax corrected to 75 yards. Centerfire scopes are typically corrected to 150 yards.
If you take the time to make sure the image is centered in the field of view, you probably won't notice a big difference in performance.

I have two .22 rifles with 1" CF scopes on them - both Weaver K 2.5X. There is little parallax with low-power scopes and mine work just fine. I would recommend using lower power CF scopes, not over 4X. You are not likely to be shooting a .22 rifle at targets more than 50 to 100 yards distant where parallax with a lower magnification scope is not an issue.

If you want to see how much error parallax can cause, place the scoped rifle a sturdy rest and move your head slightly up/down and right/left while looking though the scope. Make sure to keep the rifle steady.
With proper parallel correction, the crosshairs will stay centered on the target. With improper parallel correction, the crosshairs will move right/left, up/down relative to bullseye.

Rimfire scopes without parallax adjustment are generally set by the factory to be parallax-free at 50 or 75 yards. The centerfire versions are set to be parallax-free at 150 yards.
For shooting varmints in the yard it will be a non-issue, even if you have a very large yard.

I don't think you'll have any trouble with the setup as you describe it. But try it out, it sounds as though you have everything you need (except scope rings for the .22?) so it should be an inexpensive experiment.

No rings needed. It's a Brownells retro Colt marked 4X20 scope. They claim it's made by the same Japanese company that made them for Colt in the 70's and 80's.

I've seen a dozen articles and commentaries about standard centerfire rifle scopes vs. rimfire scopes over the past 40 years or so. During those same years I have had complete success using centerfire scopes on rimfire rifles, never any issues to worry about.
Parallax has never achieved dominance over my astigmatism or cataracts, before or after surgeries and lens replacements.

I’ve forgotten how but if you google you can adjust a scope to focus at whatever distance you want. I’ve adjusted a few centerfire scopes for 50 yards

So you have an AR pattern .22 LR, with a carry handle?

Yep, I've been on a retro AR kick. I've put 3 together so far. Ordered this one from CMMG years ago with a dedicated 22 upper, and standard multi caliber lower. Had it stamped as a SBR not long after buying it.
I'm still using the original lower, bolt assembly, buffer tube, handguards, and barrel.
Before and after.

Recently bought a youth-stockd CZ 457 in .22 for my 9 year old grandson, and then put on a 4X Leupold rimfire scope, parallax set for 60 yards, $300 plus rings and since we can only shoot now at about 25 yards max, it is superb for that. I used Warn rings on his CZ. We will be shooting it again this afternoon. I think as long as you mount a lower power rimfire scope with the proper eye relief for your expected target distance you will fine. But the smaller fixed scopes just look better on a .22 unless you are shooting competition. 4X is just aout right.
I do have a Win 52 I bought 30 years ago, and on that I have an old 4X Burris, but I shoot that at 100 yards and it works fine for me. SF VET

That is mostly true, plus the center-fire scope is usually adjusted to be parallax-free at 100 yards, while the .22 scope is parallax-free at 50.
Not enough to make any readily detectable difference with anything.

Many years back when the Ruger 7722 first came out I bought one (still have it)
I put a fixed 4 Leupold scope on it,never had a problem using it in all these years. I have mentioned this gun/scope before on here as a sporter that thinks its a target gun.-

I bought a Marlin 39M in the middle 60s and put a Weaver K2.5 on it and it has killed several squirrels, dirt clods and tin cans. I like it. Larry

Apropo of nothing whatsoever...don't try the reverse!
They say that experience is a great learning tool. I'm here to tell you that I didn't know diddly squat about scopes, parallax, different reticules, eye relief, or anything except those 1" dia x zillion feet long, giant objective lenses complete with flip up caps (no "uncool" rubber band types) were the epitome of great looks when I was 16 years old (1961).
I had my first centerfire rifle, a Sears sporterized Enfield, great rifle with peep rear.
One of my friends also had a cheaper version (home made) of a "sporterized" Enfield to which his dad had drilled and tapped after grinding off the charger bridge, and then mounted a 3/4" .22 LR el cheapo Tasco rifle scope. I'm pretty sure his dad was NOT involved, and I'm pretty sure that it was never fired until he asked me to try it out at the local Rod & Gun range.
Long story a little shorter....I still have a deep scar just over my right eye...first and only shot...blood everywhere...can't remember how many stiches, my Pop madder than all get out at my (and my friends) stupidity.
Still have the Sears sporter, haven't seen or heard from my teenage friend in 63 years, but centerfire scope on 22? Go for it. The reverse? Recommend don't even think about it.
Like I said...apropo of nothing...just another footnote from my early "learning gunsmithing" days.
Sorry.....no pics of friends sporter...no smart phones, cameras, or computers in those days.

I wanted to scope my Walther KKJ .22 LR and wanted a rimfire specific scope for it. I was dismayed to find that Leupold and others stopped making a lot of their scopes in a gloss black finish. I don't understand that as there are still a lot of high quality bolt action rimfire rifles being made that cry out for a gloss black finish scope.
It took me a while to find an NOS Leupold M8-4X Compact Rimfire Special scope for it. And I paid more than retail for the new matte finish version. But I wanted something that was made for a rimfire rifle and one that would be hunted with. It's a good match in weight and proportion and as is expected, has Leupold quality optics. Here's a pic.

I have used centerfire scopes on .22 rifles for years, mostly for small game hunting, and never had any problems at all. Many of them have been older Weaver K4's with crosshair or post reticles. I don't shoot a lot of small game past 100 yds., or 50 yds for that matter, and whatever parallax issues there might be at 25 yds or so are miniscule. If you're gonna use the rifle for yard critters, put your scope on it and fire away. it'll work fine.

I haven't checked the current prices on old used 1" Weaver fixed power scopes. I have at least four or five of them, I think I bought most of mine at gun shows for around $25 each. I am sure that eBay has lots of them listed. I have never had any problems with the old Weavers. They are more than adequate for most .22 users. BTW, tip-off claw mounts with 1" rings are readily available fairly cheaply. My most loved .22 rifle is a Remington 550-1 with a 1" Weaver K4 in a tip-off mount. Have owned that rifle since the late 1950s.
