Description
The AK-A18 is a solid choice if you're looking to extend your AK-74's capacity without adding unnecessary bulk to your kit. With 40 rounds on tap, you're getting significantly more firepower than a standard 30-round magazine while maintaining a profile that's still manageable at the range or in the field.
DuPont Zytel Polymer with Strategic Steel Reinforcements
The magazine body is constructed from DuPont Zytel polymer, which means you get impact and corrosion resistance without the weight of an all-steel mag. What makes this different from other polymer designs is the overmolded stamped steel feed lips paired with steel reinforcements at the front and rear locking lugs. These critical contact points take the wear, so the polymer body stays intact through thousands of rounds. The aggressive texturing on the body gives you a sure grip even when your hands are sweaty or gloved, which matters when you're managing reloads in real shooting conditions.
Spring and Follower Built for Consistent Feeding
Internally, the magazine uses a heat-treated chrome-silicon wire spring that's precision-wound to eliminate binding. Paired with an injection-molded polymer follower, this setup delivers reliable feeding round after round without the headaches that plague cheaper designs. The removable base plate makes cleaning and maintenance straightforward if you ever need to go through the mag.
Made in the USA with Real Warranty Backing
ProMag builds these magazines domestically and backs every one with a lifetime warranty against manufacturer defects. That matters because it means you're dealing with a company that stands behind what they make. The AK-A18 fits AK-74 platforms including WASR-2, Tantil, and SLR 105 variants, making it a practical spare magazine for most shooters running 5.45x39mm.

Frequently Asked Questions
Will the ProMag AK-A18 fit my specific AK-74 variant?
The AK-A18 is designed for AK-74 rifles and compatible variants including WASR-2, Tantil, and SLR 105. Most AK platforms operate with similar tolerances, though some shooters occasionally need minor fitting on the locking lugs depending on their specific rifle's build. This is normal for the AK platform and not a defect with the magazine.
How does polymer construction compare to steel magazines?
Polymer magazines weigh significantly less than steel, which adds up when you're carrying multiple mags. The DuPont Zytel used here resists corrosion and impact, eliminating rust issues that plague steel designs. The trade-off is that steel is traditional and has proven longevity, but modern polymer with steel reinforcements at critical wear points performs reliably in demanding use.
What's the warranty coverage on ProMag magazines?
ProMag backs every magazine with a lifetime warranty against manufacturer defects. This covers issues with the construction, materials, or assembly under normal use. If something fails due to a manufacturing problem, ProMag will address it.
Can I leave this magazine loaded for extended periods?
Yes. Modern polymer magazines don't develop the feed lip deformation that used to plague older designs when left loaded long-term. The injection-molded polymer follower is self-lubricating, so maintaining consistent spring pressure over time isn't an issue with quality construction like this.
