Can you fire a 5.56 round through a 7.62 AK?
This guide details the experimental process of firing a 5.56x45mm NATO round through a 7.62x39mm AK-103s rifle, as demonstrated by Polenar Tactical. It covers the mechanical predictions, the live-fire testing, and the post-firing analysis of the casing and target. The experiment highlights built-in safety features of the AK platform and the consequences of firing undersized ammunition in an oversized bore, including bullet tumbling and altered ballistic performance.
