Old Czech Brno rifles and actions

I really like the old Czech Brno rifles and actions. Here are my only two customs.
An AHR upgraded CZ550 .375, and a Chris Griesbach custom Brno ZKK 600 .30-06.
Both have good quality walnut, upgraded metal finish, custom sights. The straight comb stocks are beautiful, but I actually prefer some drop at heel like the original Brno ZKK 601 .222 pictured at the bottom. That's about all I'd change if doing it over.
