ProMag Industries is an American-owned and operated firearms accessories manufacturer and distributor. Based in California, ProMag Industries is lauded for their high-quality magazines in addition to the numerous accessories they produce. Generally speaking, it is beneficial to seek out factory magazines for your firearms. Factory magazines are manufactured by the same company, to the exact same specifications and tolerances as the originals. They are also made from the same materials, which ensures both fit and function in your firearm. However, when the aftermarket manufacturer is ProMag, you have nothing to worry about.
As noted, the ProMag Saiga 7.62x39mm 30-round magazine is designed to hold 30 rounds of 7.62x39mm ammunition and provide for a continuous feed. As with all ProMag polymer magazines, the Saiga 7.62x39mm 30-round magazine is injection molded and manufactured using only high quality Mil-Spec polymers to ensure durability. Moreover, because this magazine features a polymer construction, there is no risk of rust or corrosion, which is typically associated with steel body magazines that are typically seen alongside Kalashnikov-patterned rifles.
It is also pertinent to mention that all ProMag magazines are backed with a lifetime warranty that protects against manufacturer's defects. For details, please visit the official website of ProMag Industries.
Here is what I want you to do. First, go to your safe and open then. Next, collect any and all 10-round magazines for your Kalashnikov-patterned rifles and place them gently in the garbage can. Finally, order a couple ProMag Saiga 7.62x39mm 30-round magazines for $34.95 and fire your rifle the way it was meant to be fired.
Note: All Saiga 7.62x39mm rifles are manufactured to the same general specifications and tolerances, which means that not all Saiga 7.62x39mm rifles are identical. As such, it is possible that the ProMag Saiga 7.62x39mm 30-round magazine may require some minor fitting for proper use in your rifle. For your convenience, an instruction booklet that details the required tools and procedures for fitting is provided with all ProMag Saiga magazines. Also note that performing the suggested modifications does not void the manufacturer's lifetime warranty.
