Description
When you run standard 30-round mags on your AK, you're stopping to reload way too often. The KCI 40-round magazine solves that problem with extended capacity that keeps the action moving without bulky drums that get in your way at the range or in the field.
Steel Construction Built to Take a Beating
This magazine is manufactured from hardened steel and treated with a cation electrodeposition coating that handles rust and corrosion like a champ. The ribbed exterior with a pronounced dorsal spine gives you positive grip and control during magazine changes, even with dirty hands or adverse conditions. At roughly 0.8 lbs loaded, it weighs noticeably more than polymer alternatives, but that heaviness translates directly into durability you can count on.
Feeding Reliability Through All 40 Rounds
Inside, a high-carbon music wire spring, anti-tilt follower, and reinforced feed lips work together to push rounds toward the chamber smoothly and consistently. The anti-tilt follower keeps ammunition aligned and prevents binding, while the reinforced feed lips resist deformation that commonly causes feeding malfunctions in cheaper magazines. These internals ensure you get reliable function from round one through round forty, whether you're burning through practice ammo at the range or running drills.
What to Expect
This magazine fits all standard AK-47 and AKM pattern rifles chambered in 7.62x39mm. Like any steel magazine that starts out fresh, it may feel snug in your rifle's magazine well initially. A few loading cycles will seat it properly. The 40-round capacity adds noticeable height compared to 30-rounders, so prone shooting takes a bit of adjustment. For extended range sessions, tactical training, or anytime you want fewer interruptions between strings, this magazine delivers genuine value and solid field-proven performance.

Frequently Asked Questions
Will this 40-round KCI magazine fit my AK-47?
Yes, it's designed to work with all standard AK-47 and AKM pattern rifles chambered in 7.62x39mm. New magazines may feel snug initially in the magazine well, but this tightness ensures a secure lock. A few loading cycles will help it seat naturally. If your rifle has unusual tolerances, you may need minor hand-fitting, but this is uncommon.
How does the 40-round capacity compare to standard 30-round magazines?
You get 33% more ammunition capacity between reloads. The extra height is noticeable and will affect your shooting position, particularly when shooting prone. For range sessions and training, this extended capacity means more continuous shooting and fewer interruptions, which many find more enjoyable and practical for extended practice.
How reliable is this magazine for feeding?
The combination of a high-carbon music wire spring, anti-tilt follower, and reinforced feed lips creates a solid feeding system. The reinforced feed lips are especially important because they resist spreading or deformation over time, which is a common failure point in cheaper magazines. Expect smooth, jam-free feeding through all 40 rounds.
Does the steel construction and coating really resist rust?
Yes. The cation electrodeposition coating provides a protective layer that handles moisture, sweat, and environmental exposure well. Steel magazines hold up better to rough handling than polymer alternatives and won't crack from drops or impacts. Periodic wiping of excess carbon from shooting, especially when running suppressed, keeps them in top condition.
