The idea behind 5.8mm vs 5.56 mm is that 5.8mm is superior. During the development concept of the rifle Type 95, there was still the concept that Chinese force is the defensive force to defend the mainland, so the designers would make sure the enemy with 5.56 bullets can't use Chinese rifle (5.8) but Chinese rifle (5.8) can use NATO bullet 5.56 with less accuracy and power.
My question was whether it is still true for 191?
The rifle for export market is dedicated for 5.56 bullet obviously and totally different than the original ones that used by PLA
