Hi Rule303,

True, the CZ550 is the "New kid on the block" when it comes to a Custom Rifle but they are used extensively in Africa as you know so that is a good start. Both the other rifles you mentioned are still available and it comes down to personal choice and will depend on the amount of $$ you want to spend to start the project, the finishing $$ is up to you or the bank manager.

Cheers,

Jeff Gray
