You will be happy with an SA SG with a 5.4 ramge. My SA SG is perfect. I changed out the cmp birch with the walnut but in my experience and reading through the CMP forums 99% of recipients are very satisfied.
The turn around time was 47 days for me in April of this year, it looks like that time has been cut in half. I guess the reason is tax return season prompts a bunch of orders.
Good luck and enjoy your Garand.
