I bought such a Win M70 .223 stripper clip guide and clips from Mo's Competitor Supllies (203-775-1013 no website) long ago. The guide fit on my M70 HBV and works perfectly. Champion's Choice website may have the stripper clips for .223 but I'm not sure of other sources for the guide. I also made a stripper clip guide for my rifle from a Weaver one piece base that I cut a piece from and hand cut the slot into. It didn't work as well as the Mo's guide but I could leave it on the rifle when I wanted to mount a scope.
