Yugo AK Magazine
One of the best AK magazines available on the market
These magazines are built like a tank!
They have a a bolt hold open feature, a special follower that stops your bolt in the rear position on the last round fired. When you remove the magazine the bolt goes forward but it's a useful feature to let you know when your rifle is empty.
The "downside" of the mags is that they are a bit heavy and can develop surface rust if not oiled.
Surplus item, may show some signs of use, very good condition.
