The original 77's made from 1968-1991 had a claw extractor, but button ejector and the cartridge rim was not grasped by the extractor until it was in the chamber. Those were not true CRF.

The very 1st few months of the MK-II's had the true CRF ejector, but the extractor still did not grab the rim until after the round was chambed. This was corrected within a few months. It is possible to see a very few Mk-II's that are not true CRF, but all other MK-II and Hawkeye's made since 1991 are true CRF.

The confusion is that at times Ruger, as well as almost all modern CRF rifles do not always have the extractor grab the rim while it is still in the magazine. At times the cartridge jumps up out of the magazine and there is a very slight delay before the extractor grabs the rim. This happens just as often with any CRF rifle except some of the WW-2 era military rifles. This does not exclude the design from being called CRF.
