This is a factory-style 7-round magazine built specifically for the Marlin Model 922M .22 WMR semi-automatic rifle. It's manufactured to match the original 922M's dimensions and feed geometry — it is not a universal .22 WMR magazine and is not designed to fit any other Marlin model.
Fits this rifle
This magazine is engineered for the 922M action and magazine well only:
- Marlin 922M (.22 WMR semi-automatic)
Not sure which one you have? Confirm the model number stamped on the left side of the barrel before you order, or use the Marlin Magazine Fitment Guide.
This magazine is built for the semi-automatic 922M only. It does not fit the bolt-action .22 WMR/.17 HMR Marlins, and it does not fit any Marlin .22 LR rifle.
Why the exact fit matters
A magazine that's close but not quite right causes the two most common magazine problems: rounds that don't feed cleanly, and a magazine that won't drop free or lock in place. Because this magazine is manufactured to the original Marlin factory pattern — not scaled or estimated from a generic blank — the feed lips, follower geometry, and latch dimensions match what your rifle was built around. That's the difference between a magazine that works every time and one that needs to be "worked in."

Buying guidance
The Marlin 922M has been out of production for years, which makes original factory magazines hard to find. This factory-style replacement holds to the original 7-round configuration rather than an unverified extended or high-capacity claim, so you get the same feeding reliability as the original. If you’d rather run nickel, see the 922M magazine in nickel plate.
Care and installation
Insert the magazine until the catch clicks and confirm it's seated before you chamber a round. Wipe down the exterior and follower periodically, especially after a wet range day or a hunt — even a corrosion-resistant finish benefits from basic upkeep. For a full rundown on cleaning and storing your magazines between seasons, see our Rifle & Magazine Care and Maintenance guide. If you still have questions about fit after checking the model number on your barrel, contact us and we'll help you match it.
Magazine capacity limits vary by state, and some states cap magazine capacity regardless of caliber. Before you order, check your state’s magazine capacity laws.
Frequently asked questions
How many rounds does this magazine hold?
This magazine holds 7 rounds of .22 WMR.
Does this fit any Marlin rifle other than the 922M?
No. This magazine is built for the Marlin 922M semi-automatic only and is not a universal .22 WMR magazine.
Will this fit a Marlin .22 LR rifle?
No. This is a .22 WMR magazine built for the 922M only. It will not fit any Marlin .22 LR rifle.
Black oxide or nickel — which should I pick?
Both are the same 7-round factory-style 922M magazine. Black oxide gives a matte finish; we also carry this magazine in nickel plate.
