This guide details a ballistic comparison between the AR-15 (5.56x45mm) and AK-47 (7.62x39mm) using concrete blocks as targets. The test, conducted by firearms influencer Edwin Sarkissian, demonstrates the superior barrier penetration and destructive capability of the 7.62x39mm round against concrete, while the 5.56x45mm round shows less effectiveness in this specific scenario.

Quick Summary

In a ballistic test by Edwin Sarkissian, the 7.62x39mm round (124 grain) from an AK-47 proved more effective at destroying a concrete block than the 5.56x45mm round (55 grain) from an AR-15. While the 5.56mm round fragmented, the 7.62x39mm round caused structural failure and broke the block.

Frequently Asked Questions

How do 7.62x39mm and 5.56x45mm rounds compare against concrete blocks?

In a test by Edwin Sarkissian, the 7.62x39mm round (124 grain) from an AK-47 caused significant structural failure, breaking a concrete block. The 5.56x45mm round (55 grain) from an AR-15 created an entry hole and fragmented but did not penetrate the block's second wall or cause major damage.

Which rifle platform, AK-47 or AR-15, performed better in the concrete block test?

The AK-47 platform, firing the 7.62x39mm round, demonstrated superior performance in destroying the concrete block. The AR-15, firing the 5.56x45mm round, showed less effectiveness in penetrating and destroying the barrier in this specific experimental setup.

What are the key differences in ammunition used for the AK-47 and AR-15 in this test?

The AK-47 utilized 7.62x39mm ammunition, specifically a 124-grain projectile. The AR-15 was tested with 5.56x45mm ammunition, using a 55-grain projectile. This difference in grain weight and caliber contributes to their distinct performance characteristics against barriers.
