I've never seen a Kaw unit first hand, but it would appear the main difference is the Tromix 2-piece design versus the monolithic design of the Kaw.....which of course makes the Kaw cheaper to produce.
However, I imagine the functionality is about the same.
The Tromix 2-piece design allows us to stock the rear ends in various thread pitches and the front ends in various exit holes, that way we can mix and match the two in order to get whatever thread pitch and caliber combination the customer might need. We can assemble about 900 different combinations considering we also have black, stainless, and two-tone. For example, we can quickly assemble a 3/4-24 22 caliber device for a big bull barrel if need be.
