The Kestrel 5.56 seems like a good compromise, but it's exactly that; a compromise. It's made of steel instead of inconel so it's weaker than a normal 5.56 can, and yet it's still heavier than most 5.56 cans. And it's also louder than other 5.56 cans from the tests I've seen.

So it seems to me that the Kestrel is a mediocre 5.56 can at best. Sure, it can be used with .22 because it can be taken apart (though I don't know how difficult it will be to take it apart when leaded up), but it's heavier and louder than a normal 5.56 can, and even a normal-weight 5.56 can is too heavy to comfortably use on a .22.
