Sig Rattler questions

[Strykervet]

I'm interested in the new Sig Rattler, it's gotta be the shortest .300 BLK made and it's a lot lighter than a Honey Badger. Only concerns have to do with barrel length, with a 5.5" barrel does it cycle reliably and can it stabilize bullets ranging from 100-220 grains sufficiently enough to use a suppressor?

It's significant;y heavier than the Honey Badger.
