AR-15 vs AK-47 vs 100lbs of CONCRETE!!! (Penetration Test)

Published on December 4, 2023
Duration: 17:20

This video conducts a concrete penetration test comparing the AR-15 (chambered in 5.56x45mm) and the AK-47 (chambered in 7.62x39mm). The test utilizes 100lb concrete slabs within 5-gallon buckets. The results indicate that the 7.62x39mm caliber is significantly more effective at penetrating hard barriers like concrete compared to the 5.56x45mm caliber.

Quick Summary

In a concrete penetration test comparing the AR-15 (5.56x45mm) and AK-47 (7.62x39mm), the 7.62x39mm caliber proved superior. The AK-47 penetrated a 100lb concrete slab in about 35 rounds, while the AR-15 required approximately 65 rounds, demonstrating the 7.62x39mm's greater effectiveness against hard barriers.

Frequently Asked Questions

Which rifle caliber is better at penetrating concrete, 5.56x45mm or 7.62x39mm?

In a concrete penetration test, the 7.62x39mm caliber, typically used in AK-47 platforms, proved significantly more effective than the 5.56x45mm caliber used in AR-15s. The AK-47 required about 35 rounds to penetrate a 100lb concrete slab, while the AR-15 needed approximately 65 rounds.

What were the specifications of the concrete used in the AR-15 vs AK-47 penetration test?

The test utilized 100lb concrete slabs contained within 5-gallon buckets. The concrete was described as hand-mixed and estimated to be about 16 inches deep. The presenter suggested this thickness might exceed that of typical concrete walls found in structures.

How many rounds did it take for an AK-47 to penetrate a 100lb concrete slab?

During the penetration test, an AK-47 chambered in 7.62x39mm successfully penetrated a 100lb concrete slab after approximately 35 rounds were fired into it. This demonstrated its superior capability in defeating hard barriers compared to the 5.56x45mm caliber.

How many rounds did it take for an AR-15 to penetrate a 100lb concrete slab?

An AR-15 chambered in 5.56x45mm required a significantly higher number of rounds, approximately 65, to penetrate the same 100lb concrete slab. This highlights the difference in hard barrier penetration capabilities between the two common rifle calibers.
