Never Scoped a Rifle Before

So my uncle gave me a Marlin model 25 in .22 mag. I picked up a Simmons protarget rimfire scope to throw on it, cause it seemed good and I'm a fool. I later found out that they make a scope specifically for .22 mag but I'm sure that's not a big deal. Anyway, it said it used weaver-style rings and that's what my uncle told me to get, I never saw any mention of the width of the mount or anything.

Anyway, I tried to mount it today and it's too big, the rails that are cut into the receiver at a distance of about 11mm from each other, I think my rings only go to about 15-18, I didn't measure.

So before I go and buy more rings to replace the ones it came with, I'd like to know what I should be looking for, mistakes to avoid, tips for leveling, anything you think a complete newbie should know before doing something stupid.
 
3/8"(11mm) rim fire rings is what you need to fit the grooved receiver, you could buy adapters to use the rings you have but rim fire rings are pretty inexpensive and will be better.

What height rings did you buy for the weaver's you have now? Does it look like it's a good height match for you rifle and scope?
 
Two different things!!! 11mm top width are usually a European thing - use a 60 degree dovetail angle. 3/8", as they are called, actually measure real close to 1/2" wide at the widest, and use a 45 degree angle. The "3/8"" part is the distance between the tips of the cutters that made the dovetail - at the bottom of the dovetail - nearly impossible to measure accurately with normal measuring tools. Some ring makers, like Warne, make rings that you can flip the side piece to match up to either width - some do not. When selecting rings, also have to consider bolt handle clearance - most people looking at clearance to the barrel at the front end, like I was doing, until I had perfect clearance at the front, but bolt handle would hit the eye piece....
 
By the way - if you have picked up a Simmons Pro-target, that is a decent scope from the Simmons line-up - do not just dismiss it.. I think that one had an Adjustable Objective for parallax error, if I am thinking of the same scope. Simmons did market a "22 Mag" scope - just marketing - nothing really to do with quality or the application for the scope. Depending what you paid for it, you could have selected much more inferior products. Mount it correctly and give it a chance - I think you will be surprised!!
 
Potashminer is correct 11mm is a slightly different euro metric standard, BKL makes nice rings that fit both 3/8 and 11mm.
Your made in America Marlin will be a 3/8" rimfire groove.
 
Idk what height they are, if I had to guess I'd say they're about 3/4s of an inch tall? Scope's back in my cabinet and I'd have to pull it all back out to check. I think it's good enough for my bolt handle to not worry about, and I at least know I want the scope as close to the barrel as possible. I'll check tomorrow to be sure.

Specifically, I have a 4x32 ProTarget Rimfire scope, I got it for about 50 bucks. Comes with some kind of polarized/low-light lens cap, which looks like it might be nice to have. Tenda was and is having a big sale on them so I figured it was a safe bet. My uncle recommended me to get nothing more powerful than 4 power, especially for rimfire.
 
I dug out the Simmons scope that I was thinking about - might not be the same, any more? This one says "Korea" on the side, and around the front bell, it reads "Simmons 22 Mag Target Scope". It is a 3-9 variable power - possibly 32 mm objective or so. Model No. 899621. 1" scope body. FWIW, I agree with your Uncle - for general use, is hard to beat a 4 power scope on a .22. I just installed a Leupold FX-1 4x28 on my little CZ 452 Scout - little rifle, little scope - looks like they will work together well.

Lower power if your using it for shorter ranges. I use to think 4 power was all you needed until I started shoot ground hogs out to about 150 yards. They dig holes in the horse pastures which the horses can run and step breaking a leg. Normally the horse has to be put down. GH are shot when ever I see them. I am currently using a 4 to 12 and I am wondering about going bigger.
 
So I yanked out the scope and my rifle, did some measuring, the rings are high enough that the bolt handle has plenty of space to work without hitting the scope. I measured the height of the rings, and found that they're about half an inch to the bottom of the scope tube. I forgot to measure the scope tube, and it seems to be about one inch in diameter, which lines up with what I see online.

So I need some rings that are 11mm wide at the grip, 1 inch tall, and 1 inch in diameter. Any brands I should look for? I found some black metal Burris rings that seem alright, but they're 0.8 inch and I think that's a bit too short, probably gunna stick to 1 inch.

I disagree with your uncle.
If you want tight groups, or some distance shooting (even just at 100 yards) 4 power is, in my opinion, nowhere near enough power.

Shooting squirrels in a tree, ok.
