About this product
The Valmet M78 magazine is a factory-pattern 20-round box magazine built for the Valmet M78, the Finnish semi-automatic rifle chambered in .308 Winchester (7.62x51mm NATO) that Valmet built on its AK-derived action. It locks into the M78's magazine well the same way any AK-pattern box magazine does: hook the front lug into the trunnion and rock the rear back until the catch clicks. Because it holds 20 rounds, this magazine falls outside what California law allows a dealer to sell or transfer to a resident, so treat this listing as reference information rather than an in-state purchase option.
What is it used for?
It's a spare or replacement magazine for anyone who already owns a Valmet M78 or Valmet-pattern .308 rifle and needs extra capacity for range sessions, hunting, or simply having a working spare on hand. Valmet magazines are less common than standard AK 7.62x39 magazines because the M78 itself was produced in smaller numbers, so a functioning original or well-made pattern magazine is worth having if you shoot the rifle regularly. It is not a universal AK magazine — it is sized specifically for the .308-length action, which is longer and wider than the 7.62x39 or 5.56 variants of the same rifle family.
What fits it?
This magazine fits the Valmet M78 rifle chambered in .308 Winchester / 7.62x51mm NATO, and generally interchanges with other Valmet-pattern .308 rifles that share the same magazine well dimensions, such as certain Valmet Hunter variants built on the same action. It will not fit standard 7.62x39 AK-platform rifles, 5.56 Valmet Hunter models, or Galil-pattern rifles despite the family resemblance — the feed lips and body width are cut for the larger .308 case. If you're not certain your rifle takes this exact magazine, check the factory manual or have a gunsmith confirm fit before buying, since a mis-sized magazine can cause feeding failures.
How does it compare to other .308 AK-pattern magazines?
Valmet-pattern magazines are generally regarded as well-made compared to many aftermarket AK-family magazines, since Valmet built its rifles to tighter tolerances than most Soviet-bloc factories. Original Valmet steel magazines are harder to find than Galil or R4/R5 .308-length magazines, which share a similar lineage but are not directly interchangeable. If you can't source a factory Valmet magazine, some shooters report modified Galil .308 magazines fitting, but that's not something to count on without hands-on fitting.
Does it work in California?
No — a 20-round magazine cannot be sold to or possessed by a California resident under state law, which caps magazine capacity at 10 rounds. If you live in California, ask us whether a compliant 10-round Valmet-pattern magazine is in stock instead; we cannot ship this listing to a California address. See our California gun laws page for the current rules on magazine capacity and how they apply to out-of-state purchases.
Who is this not for?
This isn't the magazine for someone shopping for a first AK-pattern mag — it's a specific fit for a specific, fairly uncommon rifle, and buying the wrong magazine for a similar-looking gun wastes money and causes function problems. It's also not for California residents for the capacity reason above, and it's not a fit for anyone hoping to use it in a standard 7.62x39 AK, since the case dimensions don't match.
Is it worth buying?
Because pricing and availability change with supply, the honest answer is that it's worth it if you own a Valmet M78 and need a working spare — factory-fit magazines for this rifle aren't something you'll find at a big-box counter. Contact us for current price and stock before ordering, and confirm your rifle's exact chambering and magazine-well dimensions match before you commit.

Frequently asked questions
- Is this a factory Valmet magazine or an aftermarket copy?
- Listings like this are typically surplus factory-original Valmet magazines rather than new production, since nobody currently makes new Valmet-pattern .308 magazines. Condition varies by unit, so ask about finish wear and feed-lip condition before buying.
- Can I get a 10-round version for California?
- If a 10-round Valmet-pattern .308 magazine is in stock, that's the version we'd sell to a California address. Ask us to check current stock on the compliant version.
- Does this magazine fit other .308 rifles?
- Only rifles built on the same Valmet-pattern action with a matching magazine well — it won't drop into a standard AR-10, FAL, or M1A.
- How do I maintain a steel AK-pattern magazine?
- Wipe it down, check the feed lips for spread or damage, and function-test with dummy rounds before you trust it at the range. Retire any magazine that won't lock the bolt back on empty or lets rounds nose-dive.
- Will an old surplus magazine still be reliable?
- Most surplus magazines function fine, but springs weaken over decades — a spare spring set is worth having on hand for an older magazine like this.
