This comparison between the AR-15 and AK-47, conducted by 4MR Ranch, evaluates their performance against cinder blocks and water jugs using specific ammunition. The AK-47 demonstrated superior penetration against hard targets and better straight-line performance in soft targets, attributed to its heavier 123-grain 7.62x39mm ammunition compared to the AR-15's 55-grain 5.56mm XM193. The presenter notes this is for entertainment and not a scientific study.

Quick Summary

The AK-47, firing 123-grain 7.62x39mm ammunition, demonstrated superior penetration against cinder blocks, shattering the first block. In water jug tests, it penetrated four jugs, maintaining a straighter path. The AR-15, with 55-grain 5.56mm XM193, penetrated the first cinder block but only dented the second, and only two water jugs, due to the bullet's tendency to tumble.

Frequently Asked Questions

How did the AR-15 perform against cinder blocks?

The AR-15, firing 55-grain XM193 5.56mm ammunition from a 16-inch barrel, penetrated the front of the first cinder block, creating a large crater and an inch-diameter hole. It then hit the second block's internal wall with only a slight dent, showing limited penetration.

What was the AK-47's performance in the cinder block test?

The AK-47, using 123-grain Wolf FMJ 7.62x39mm ammunition, significantly outperformed the AR-15 by completely shattering the first cinder block and separating its back. While it didn't fully penetrate the back wall, it caused extensive damage.

Which rifle penetrated more water jugs?

The AK-47 penetrated four water jugs with its 123-grain FMJ ammunition, maintaining a straighter path. The AR-15, with its lighter 55-grain XM193, only destroyed two jugs, with the bullet theorized to tumble or veer upon impact.

What ammunition was used for the AR-15 and AK-47 tests?

For the AR-15, 55-grain XM193 ball ammo (Federal, brass case) was used. The AK-47 was tested with 123-grain full metal jacket (FMJ) steel-case ammunition, likely Wolf, to match the platform's origin.
