I use the Ted Cash Rev-B also. Works great on my Knight MK's. I also have a couple straight line cappers as well that I used for years and years, and they worked fine too. I got the Rev-B capper in a Knight accessory kit that I picked up a while back, otherwise I probably wouldn't have bought it, what I had worked fine. But I do like it. Knight used to sell them as the preferred capper for thier rifles. It definitely holds alot of caps.
