Some questions come to mind.
Is this the only host/caliber you plan to use the suppressor with?
Do you want a direct thread or a quick detach type of mount?

I have a Palmetto State Defense .223 can that is direct thread. It is used on any of my .223 platforms including my 10.5”SBR. It handles .204 ruger as well.

You could go up to a 30 caliber can which gives you options from .223/5.56 - 6mm - 6.5mm - 30 cal (all the way up to 300 win mag).

Go look at Capitol Amory’s website as well as SilencerShop. There is a heap of info and pictures to take a gander at.

There are quite a few companies that make .223 suppressors most of which will do a good job for you.

Don’t get caught up in the obsession of details...you’ll never end up getting one.

Where are you located ? Is there a shop near you that is a class 3 dealer that can handle the transfer ?

Are you going to transfer it as a trust or individual ?

Those are all factors besides which can.
