I think that is the part he is not getting. The barrel will have to be removed from the gun, chucked in a lathe, the muzzle turned down and threaded. You may be able to find a suppressor with the same finish and diameter so it will look like a LOONG bull barrel. Shouldn't call it a bull barrel then. INHO a bull barrel is very heavy and shorter than normal. A heavy barrel is heavy and as long or longer than normal.

A 24" heavy barrel on an AR is a heavy barrel not a bull barrel.

I understand I need the barrel threaded but I didn't know where to find a can that would fit around my barrel

ZOMG!

the can attatches to the threads on the end of the barrel. They do not fit around the barrel. Any can rated for 223 with 1/2"x28 threads will fit your gun.
