Specifically talked to Dale about his cans, and attachment. VERY smart attachment system. The suppressor host/flash suppressor is threaded outside, in a similar fashion as the AAC suppressor hosts. The can itself is threaded, and screws onto the host. I directly asked if the outer threading was the same (i.e., the can threads) on the 5.56 suppressor and 7.62 suppressor. Answer: "YES! Use the 7.62 can on a 7.62, 6.8 or 5.56 rifle - we designed it that way."
However, here's the bonus - there's a thread-on "sheath" that serves as a thread protector, and kinda like the Noveske Pig - directs ALL your blast forward.
