CZ has taken the Bren 2 design, and scaled it up to 7.62mm NATO as the Bren 2 BR (Battle Rifle). A decent number of military and security organizations are still interested in the larger cartridge, including the Hungarian military and Kenyan game rangers. Essentially this is the same mechanism as the 5.56mm Bren 2, just scaled up a bit. It does use SR-25 magazines (including the Magpul 7.62 pattern), but CZ makes its own 25-round version.
In addition, the Czech military has adopted a semiauto-only version of the BR as its new marksman’s rifle, but that is a subject for a different video.
