Your bolt has a lip at the end of the hood for extracting the red plastic jacket... the 2011 conversion bolt is minus that lip.
This picture shows the lip on the bolt... on a Western Bolt the lip is gone and the opening is a bit larger. The lip can get in the way of some cappers...
I am pretty sure - but not positive - if you order the Big Horn 52 cal cap breech plug.. it will be a few thousandths to long to work in the DISC.
If you can get them to mail you a Western Kit Breech plug - you may get away with just that even with the lip on the current bolt.
