I'm not the most knowledgeable on this board, perhaps someone else may provide more clarity. All I can tell you is that on a Savage 12FV in a Choate Tactical Stock with CDI bottom metal and MTD 223 polymer magazine, the bolt comes all the way back and cycles rounds properly from battery through ejection. Is that what you're asking? Sorry, I haven't a clue what a 223 baffle is?
