Seems there are few that are CRF. The AICS is a single stack magazine. Some of the actions are actually cut for AI AW magazines, which are true double-stack. Some actions give the option between AICS or AW. If you buy one cut for AW, it tends to work with AICS as well, but you typically need to do some work on the magazine catch on your bottom metal. I believe Manners offers a different magazine catch for AW cut vs AICS. They sent me one of each on my last order.All the actions cut for aics mags do it. Mausingfield is another
Works fine in my Big Horn, but I could see it would be difficult with a full-length Mauser "claw".I’m a true AW style double feed CRF could be tricky.
