I was a bit ambivalent to the BREN at first, but seeing how CZ greatly improved the design between the BREN 805 and BREN 806, I think there is a case to be made that the company (CZ) knows how to take real-world experience and then shape that into an improved product in relatively quick order.
Moreover, CZ's changes to the BREN 1 (which resulted in the BREN 2) were borne out of experience in Afghanistan; it's not often we get a tacit iteration based on real world experience so soon.
Beyond that, I was impressed by the modular chamber design of the BREN. With a few adjustments the same core rifle design can be adapted from 5.56 NATO to 7.62x39mm and even 7.62 NATO.
I know the venerable Russian designs are rock-solid, but if we want to scale a single design as widely as possible, a legitimate argument can be made towards going for a multi-chamber'able design such as the BREN or SCAR. We can invest in the one rifle, and then distribute it to practically every military service arm, law enforcement agency, and paramilitary unit in the country (over a period of several decades of course).
Between the SCAR and the BREN, the BREN is cheaper, but still very good in its own right. Moreover, we could perhaps link the BREN to a large enough purchase of Meopta sights and other optics technology, perhaps produce those under license at home as well.
