They call it a "reusable carrier". I don't know why they do this. Even though the Traditions Pursuit came with a terrible trigger they at least do not use the extra piece to hold the primer. It just fits in the removable breechplug just like in the T/C Omega. No carrier, no plastic thingy, no problems. It is also possible to make the conversion on either the Omega or the Pursuit to the .25ACP rifle primer.
