Dogfish,

Yes it does. If you buy a new gun with the wrong breech plug then just call Knight. (you probably won't find one with the right one) they will send you the right stuff at no cost if it's not used. it's called The Western Disc conversion system. basically it is just a breach plug that will allow you to use the caps that we need to use. I really like my disc extreme. it shoots good and I don't have one of them goofy bolts you pull back to cock it. it's like a normall rifle with a fireing pin. the only complaint I have is the trigger pull. I am use to good triggers in my custom guns. Every ML I have shot had a bad trigger. IMO If ididn't buy the Knight I think i would buy the Rem 700 ML I like the way they feel in my hands.

I shoot .50 cal with a sabot made by Precission Rifle Bullets. It's .45 cal and shoots really flat. I can't remember what wieght but it's blue. I think it's around 300 grn. I have been shooting 110 grns of Hog. triple 7 FFF I just havn't taken the time to try it hotter. It shot great @ that so I went hunting. this summer I will try working up to the max and see how it groups.
