This is the KCI AK-47 7.62x39mm 10-round magazine. 

When you have only ten rounds, you want to ensure that your magazine is as durable and reliable as possible. 

This 10-round magazine from KCI is constructed from stainless steel and features a corrosion-resistant finish for maximum durability. Inside the magazine, you’ll find a high-quality steel spring and polymer follower that work perfectly to provide flawless feeding. 

Each floor plate is laser-welded to further strengthen the magazines. Just in case you still feel they may not be durable enough, each magazine is backed by a lifetime warranty. 

Why not grab a few since they only hold ten rounds a piece?
