Frequently Asked Questions

What are the key ballistic differences between the AK-74 and AK-47?

The AK-74 fires the 5.45x39mm round (65 grains, 2900+ fps), which is lighter and faster, while the AK-47 fires the 7.62x39mm round (123 grains, 2300 fps), which is heavier and slower. This difference significantly impacts terminal ballistics.

How does the AK-74's 5.45x39mm round perform in ballistic gel compared to the AK-47's 7.62x39mm?

In ballistic gel tests, the 5.45x39mm round from the AK-74 demonstrated immediate tumbling upon impact, creating a much larger wound channel. The 7.62x39mm round from the AK-47 tumbled later and less dramatically.

Is the recoil significantly different between the AK-74 and AK-47?

According to the expert analysis, the felt recoil between the AK-74 and AK-47 was surprisingly similar, despite the differences in caliber and bullet weight. This suggests other factors contribute significantly to the shooting experience.

What makes the AK-74 considered 'leaner and meaner' than the AK-47?

The AK-74 is considered 'leaner and meaner' due to its development around 1974, featuring the smaller, faster 5.45x39mm cartridge which, as demonstrated, exhibits superior terminal ballistics through rapid tumbling and effective energy transfer.
