The new Ultimate Slam Muzzleloader will not inter change Breech plugs or bolts with any current Knight Muzzleloaders. That only makes sense to me, and all employee's know this now. Sorry for any confusion.
Grouse... I kinda figured the new breech plug alone would not interchange since it's too long for the current Extreme bolt... but thought the new breech plug plus the new bolt would work.. ?
I'm not happy... I have a .50 & new .45 Elite just waiting for the conversion. Knight just lost a nice hunk of $ from me on the conversions.
