Description
If you run an AK platform rifle, adding extra capacity to your magazine collection makes sense, and this 40-rounder from ProMag delivers solid performance for the price. The magazine body and follower are molded from DuPont Zytel based polymer, a material known for standing up to real-world use and impacts that would crack cheaper plastics. The spring is wound from heat-treated chrome silicon wire, which resists deformation and keeps feeding smooth across hundreds of rounds.
ProMag AKA19 Design and Build
The polymer construction keeps things light compared to steel mags, which matters when you're loading up spares. You get that extra 10 rounds over a standard 30-rounder in a package that won't weigh you down. The body features aggressive texturing on the sides that makes it easier to grab and manipulate quickly, even with gloved hands. The injection-molded follower ensures rounds stack properly and feed without tilting or binding, which is critical for reliability.
Capacity and Fit
At 40 rounds in 7.62x39mm, this magazine slots between standard 30-round mags and high-capacity drums. It's designed to work with most common AK-47 pattern rifles, though it won't work with unconverted Saiga rifles. Made here in the USA and backed by ProMag's lifetime warranty, it's a straightforward spare or backup magazine for range use and equipment readiness.

Frequently Asked Questions
Will this 40-round magazine fit my AK-47?
The ProMag AKA19 is designed to fit most common AK-47 pattern rifles chambered in 7.62x39mm. It won't work with unconverted Saiga rifles. If you have a standard AK variant from a major manufacturer, you should be good to go.
How reliable is the ProMag AKA19 for range shooting?
Users report good feeding and function through hundreds of rounds at the range. The heat-treated spring and injection-molded follower work together to keep rounds stacking and feeding smoothly. Like any polymer magazine, proper maintenance and not leaving it loaded for extended periods helps keep it performing.
Is this magazine made in the USA?
Yes, the ProMag AKA19 is manufactured and assembled in the USA. It comes with ProMag's lifetime warranty and is built to handle routine range use and equipment readiness.
What's the difference between the 40-round and 30-round ProMag magazines?
The AKA19 holds 10 additional rounds compared to a standard 30-round magazine, giving you 33 percent more capacity in roughly the same footprint. The extra height and slightly different profile matter less for range bags, but they can be bulky if you're trying to reload quickly from a pouch during standing drills.
