Here are a few. David Miller Co., D'Arcy Echols & Co., Gene Simillion, Matk Penrod, Dakota Arms, Kimber, Hartman & Weiss, Rigby, Holland & Holland, and his list could go on for miles.
CRF is just a small part of the equation, there are a bunch of other features that these actions have that makes them, in my opinion, superior. A large claw extractor that has been timed correctly is a wonderful asset to feeding and is more positive in extraction. It also is much more forgiving in dirt, wet, and cold. The bolt face is another asset. There are no itty bitty springs or plungers to gum up or freeze, or take brass etc. a fixed blade ejector is superior in every way. Many of the CRF actions ave superior safety systems and fire control systems. I've seen weather conditions cripple enclosed trigger systems while my model 70 keeps on ticking. Integral recoil lugs and large flat bottom receivers are another plus. Field strippable firing pin assemblies and robust firing pins another.
You never have CRF actions sent to gunsmiths to add features of most popular push feeds. The opposite has spawned a carriage trade all on its own.
