Frequently Asked Questions

What is the main caliber difference between an AK-47 and an AK-74?

The primary caliber difference is that AK-47 variants typically use the 7.62x39mm round, while the AK-74 utilizes the smaller 5.45x39mm cartridge. This change was part of a Soviet effort to adopt a round similar in concept to NATO's 5.56mm.

How can I visually distinguish an AK-47 magazine from an AK-74 magazine?

AK-47 magazines, designed for the tapered 7.62x39mm round, have a more pronounced 'banana' curve. AK-74 magazines, for the straighter 5.45x39mm round, are noticeably straighter, though they still retain a slight curve.

What are the thread differences for muzzle devices on AK-47s versus AK-74s?

AK-47s commonly feature 14x1 left-hand threads directly on the barrel. In contrast, AK-74s typically use larger 24x1.5 right-hand threads, which are integrated into the front sight block assembly.

Are there internal differences between the AK-47 and AK-74 bolt carriers?

Yes, a key internal difference is the bolt carrier. AK-74 bolt carriers often feature a distinct lightening groove cut into the side, a feature generally not found on standard AK-47 bolt carriers.
