The ejector was machined into the receiver on the k98, on the ruger, its a pivoting type. The Ruger MKII also has integral scope mounts. It is in my opinion, that the 77MKII action is the finest rendition of the k98 a hunter can hope to have...and yes i have a pre 64 winchester. The only problem with the MKII is the trigger. It is total crap. It can be fixed easily with polishing or a drop in, but in factory guise, its one of the worse on the market.
But Yes, the original 77 was a push feed with claw extractor, plunger garand type ejector, and tang saftey. They were also available without the integral scope mounts.
