AK-47 VS AR-15 - 7.62 VS 5.56 VS CONCRETE BLOCK
This video compares the barrier penetration capabilities of the AK-47 (7.62x39mm) and the AR-15 (5.56x45mm) against concrete cinder blocks. The 7.62x39mm round demonstrated superior performance, causing the block to structurally fail, while the 5.56mm round only created an entry hole and fragmented internally. The test highlights the kinetic energy advantage of the heavier 7.62x39mm round for defeating cover.
