Yugoslavian BHO (Bolt Hold Open) magazines for the AK-47 used to be fairly widely available at reasonable prices. They have become harder to find lately and the prices have risen accordingly. Now it is appears there is a new option on the market for those who like the BHO functionality of these magazines.
Apex Gun Parts is selling a new Croatian BHO magazine and it appears to a great value. These blued steel magazines modeled after the Yugoslavian BHO magazines and come in rust inhibiting packaging (not heavy cosmoline). At $10.95 each, they are more affordable than any Yugo mags I have seen recently, if they can even be found.
