They are doing the same thing TC has been doing for years and CVA started doing a few years ago. Exchange-a-barrel systems. Wonderful idea of course. Question is what will the price tag be? TC set the standard and CVA made one (not quite as good in my opinion, but still good) for less. Wonder if Knight is going to try and go above or below. My guess would be above. When inlines first came out, there was ONLY Knight (who still has an LK-93 Wolverine...I do). Simple, cheap and deadly. Now, they are complicated and god awful expensive. Lost a fair piece of the market share. We'll see.
