-Yes but is it a true CRF?...what distance does the feeding cartridge have to travel before the claw properly engages the rim?

you'd be surprised how many people think they have a CRF functioning rifle , that in reality operates like a push feed for some distance
before the claw properly engaging the cartridge rim....all my M70 classics and numerous others that I've seen, did not effectively engage the
rim for maybe a third (or more ) of the follower/magbox length... people on other forums have highlight the same issue with their 'CRF" rifles.

and is the extractor claw undercut?....
because thats a design feature that contributes much to the reliable and positive extraction of a CRF.
