Notice: As of April 2026 these magazines now have Black Oxide finish instead of Nitride.
Black oxide is smoother, but less corrosion resistant, wipe magazines with oil rag after use.
This was done to improve loading and feed performance with a wider selection of ammo.
Read the ammo selection note near bottom
One free loading tool included with each order.. Comes folded into packing slip.
Video on how to use loading tool HERE
20 round capacity for the MK II bolt action by savage. Also fits Lakefield Mark II rifles since they are basically the same.
Does NOT fit the Savage 62 64. If you think it might fit a rifle not listed above please ask BEFORE ordering.
These magazines are fully laser cut, and are welded instead of crimped together.
View holes at 3,5,10,15 and 20.
Magazine is Carbon steel with a black oxide finish, stainless steel follower.
Please note we suggest a break in process as shown in video below. Magazine feed will be slightly sticky the first couple uses.
Ammo selection:
Please note that some longer bullet profiles result in stiff loading and sluggish feeding as the added length causes binding in the magazine.
Here is a sample of bullets we have on hand. Both the ones indicated with the arrows did feed, however it is difficult to load to 20 rounds.
Some ammo will only work loaded to 10 or 15 rounds. If you use the correct loadings, the magazines load easily.
Interestly many bulk pack loadings cycle very well.

Rimfire magazines are restricted in many cases just like centerfire.

Well, is my face red. I was contacted by a CSS rep who told me that they had been including the loading gizmo for months and that it was tucked away in the packing slip. Being a man and loathe to open and read anything, I took out the mags and threw everything else away. I've asked CSS if they can send me a new one and I suspect they will. Any company that is reading and responding to reviews on a Sunday is showing great customer interest IMO.

.....you better not be in a hurry to load them. They worked and fed perfectly in my Savage M2 FVSR but the loading is really tough. I wound up using a length of dowel rod to shove the rounds down as I loaded them. I did the break in as outlined on the web site. I think I saw on the site that they have some sort of little gizmo they charge 20 cents for to assist in the loading. If the thing is that cheap, one should be included with every mag.
Csspecs: It was included with the magazine, the loading tool is in the packing slip.

I followed the suggested break in tutorial, using the loading tool to shift the cartridges up and down while fully loaded. Bought 2 magazines and have done this for probably an hour each, while also taking the rifle out to multiple shooting sessions and doing it for a few minutes each time I load a magazine as well. One is a bit sticker than the other, but both hate feeding the second and third rounds.
The build quality does seem good. The magazines are stiff, and the springs seem strong. I am happy with that, but the initial feeding is still kind of a pain, especially when dealing with new shooters. I am hoping that they will eventually break in well enough to feed all 20 rounds properly. If not, they seem like great 17 round mags lol
Using 40gr copper plated round nose Fiocchi .22LR
Also have 40gr copper plated round nose Remington on the way to try.

Works great. Harder to load than the stock mag. But still worth the money.

Follow the break in guidelines of the video and you have a great working magazine. The magazines I bought from Csspecs work a lot better than the magazine that came with the rifle, I gave the factory magazine the same break in treatment that is recommended for the Csspecs ones but it still doesn't feed as well as the larger capacity ones.

I really don't want to do a review of this magazine cuz I feel there's something I may be missing after you set and you tinker with it moving it up and down the magazine will feed with certain ammo however the extractors are not catching on the ends of the rounds so every time you load around you have to push a rod down the end of the barrel to extract shell I don't know what's going on Any input would be greatly appreciated as that is the only problem that I have with it and I will be more than happy to do a actual review if I can get a solution to that problem I would greatly greatly rate at more stars as I have been looking for more than a 10-round for this gun for 3 years I would like to also know the exact date that this magazine formerly came out for sale
Csspecs: Sounds like your extractors are missing or are damaged or are otherwise not working. I'd be happy to help you solve this since it does not sound like a magazine issue. I don't have any way of contacting you since there is no identifying information on this review. Please contact us.

I understand that I have to break the magazine in before it gets easier to slide in the ammo. But the break in was horrible, it took me so long and too much effort as the ammo got stuck and it’s really hard to push them down. The quality is top notch but it’s just too much work for me.
Csspecs: It's likely you are using ammo with a longer bullet profile, if you use the other types you'll likely find they load easy..

The loading tool is a must when breaking in new mags. After breaking them in they load and cycle without issues, I have went through couple hundred rounds so far and no issues.

These magazines are made of high quality products. They are just as described. I would purchase it again. This fits perfectly into the savage mark II.
