barrel threading question

[5MCW]

Forgive Me if this is a noobish question but, I dug around and did not find what I was looking for, a lot of other great info tho.
Going to get a replacement barrel from Shilen for My savage and was going to go ahead and get it threaded for perhaps a comp. or most likely a suppressor down the road. What threading(if that's the correct term) would be a good choice to have a wide range of choice down the road?

The standard threading is based on the caliber. .223 is usually 1/2" x28 and .308 is usually 5/8" x24. There are variations on this but these are the standards. In between calibers can go either way.

Yeah, I fail. It is a .308

get the info from the compensator or suppressor you're gonna by. Thread sizes can be larger than 5/8"x24.

It was for my 308 brake.

Can be pretty much any size, but those are the standards and are by far the most common.
