Theoretically, if they did make a 5.56 export version for the 191, where would the mag release go? The trigger guard seems to be too far forward to make a mag release easy to access.

Note STANAG magazine well on a rifle that has iterations that also accept AK magazine in other calibers.
These are three options if Norinco and China wants to make a derivative of the QBZ191 in 5.56x45mm/.223.
1) modify 5.8x42mm magazine or use AK101 /Ak201 magazines. Not impossible the round already fits the basic form of the magazine body it would need perhaps a change in curve but it’s fairly easy and frankly fairly common in commercial market for nonstandard ammo in an established weapon series. For example a number of 7.62x39mm or 5.45x39mm commercial AR15 use modified AR magazine or magazines with an AR15 magazine profile.
2) design a new magazine and well that are a bit of a hybrid. G36 and Sig 550 are examples of this. They have wells closer to STANAG but not interchangeable with it using an AK style tab.
3) a separate receiver with modified well to accommodate STANAG. The Chinese did this though arguably a bit of a cludge in the Type 97. Another version of this option is….
3.5) Design a modular lower receiver group that has a magazine well modules that could be swapped out and meet different magazine profiles. The G36 kinda has that option it’s just not used militarily. A number of commercial AR also have it again not used in wide military service.
