I ordered mine from E Arthur Brown Co (eabco.com) and it's listed as a loose powder adaptor @$19.95. On the factory website they call it the Loose Powder Primer Adaptor @ $24.95. I'm very pleased with mine so far. It's still in the 90s here so not ble to get in much range time. The original scope mounts I bought did not move the scope back far enough to get a proper sight picture so it's at my gunsmith getting new rinds and some trigger work done. The factory tigger is clean and crisp, but breaks at 3 1/2 to 4 lbs. All 3 of my Knights are set at 2 1/2 lbs so I hope he can get it down a lb. The factory won't do it and tells you not to. It is the easiest mz to clean up that I have ever owned. and the breech plug works as advertised, no blow back, etc. I use nothing but BH 209. Once it cools down I need to work up a couple of loads. It's doing fairly well with 110 gr. BH 209, Federal 209A Primer and Hornady's 300 gr. SST. I plan to try Bob Parker's 300 gr Ballistic Extreme and Harvester's 300 gr PT Gold.
