Have not had much to do with Brno actions.
So, Apart from the normal thread and bolt lug accurizing, what sort of improvement work does the Brno require ie: triggermods/change out?,safety? bottom metal options available?..etc
Thanks in advance.
Im also guessing Mcmillan only makes a blank for the magnum .375hh length receiver?...Hold on a sec, just searching I see a Mcmillan for CZm550...and I think I likes it.

other than the safety changes, the location of the trigger on the bottom metal, and the potential of a pop-up sight, these are CZ 550 actions, in todays' terms..

I have a 602 in .375HH and find that it doesn't need anything. It is very accurate, functions quite well, and the stock is a relatively attractive European walnut. I had mine shortened slightly to accommodate winter clothes, but other than this mod, it is factory and very nice. Kudude
