Duration: 7:44

This video from 4MR Ranch provides a practical, albeit informal, comparison between the AR-15 and AK-47 platforms. An experienced instructor demonstrates and discusses the performance differences when firing American 5.56mm XM193 and Russian 7.62x39mm ammunition against cinder blocks and water jugs, highlighting variations in penetration and energy transfer.

Quick Summary

In a practical comparison, the AK-47 firing 123-grain 7.62x39mm ammunition demonstrated superior energy transfer against cinder blocks, shattering the first block, and achieved deeper penetration through four water jugs. The AR-15 with 55-grain 5.56mm XM193 penetrated one block and only destroyed two water jugs, suggesting potential bullet tumbling.

Frequently Asked Questions

How did the AR-15 and AK-47 perform against cinder blocks?

The AR-15 penetrated the first cinder block with a large crater and dented the second. The AK-47 completely shattered the first cinder block and caused extensive damage to the second, demonstrating significantly more energy transfer.

What were the results of the water jug penetration test?

The AR-15 destroyed only two water jugs, with the bullet appearing to veer or tumble. The AK-47 demolished four water jugs, maintaining a straighter path and indicating better forward momentum and penetration.

What ammunition was used in the AR-15 vs. AK-47 comparison?

The AR-15 was tested with 55-grain XM193 ball ammunition (Federal, brass case, American-made). The AK-47 was tested with 123-grain FMJ steel case ammunition, likely Wolf, from Russia.

Is this AR-15 vs. AK-47 test a scientific study?

No, the presenter explicitly states this is for entertainment purposes only and not a scientific test. He acknowledges many variables that could affect the results, advising against drawing definitive conclusions.
