I've got the itch for an F1 can. (or more
)
I can file to suppress a .22, a 9" blackout, a 12.5" grendel, a 9mm, or a 12" 5.56. I'm most likely to go for 22 or 9mm, but I could change my mind.
What should I put down for can dimensions for any or each of those? It used to be easy - get the measurements off a kit and file. Now I have to know the finished size before I even find the raw stock to make it from.
Edit - did a little searching and reading - They only want caliber and length? I can specify a foot long and only build 7" if I want?
