No...5.45x39 which has much better range & accuracy than the 7.62x39.
Flatter trajectory and considerably faster.
I'm not convinced that is a practical advantage in 100yd or less tactical situations. Shooting from a bench with a scope, yes. Or farther out.
I believe it is an AK platform chambered for the lighter round. Can someone confirm that?
And yet some apparently think that 7.62 may be still superior, at least in some certain regards-like penetration or knock down power.
