Hi Adam:

I just saw your post. I've had a Brno 602 in .375 H&H for many years, and have played around with different handloads, as well as different factory ammo. So having a number of front sights to allow the rifle to shoot to POA with different loads is just common sense.

CZ's front sights on their 550s (like the .375) are identical to those on the 602 and fit the same - by way of depressing the spring-loaded detent in front of the sight. You can buy extra sights in different heights from CZ. I got about 8 of these sights from CZ-USA. Scopes are fine, but I like shooting with iron sights too. I've now got my 602 "regulated" perfectly for a number of handloads using bullets of various weights with these extra sights. Just be sure to keep good notes of which front sight goes with which of your handloads.
