The classic Mauser action has:
Two front locking lugs on the bolt that lock onto two recesses in the receiver ring.
An internal staggered magazine.
A long external rotating extractor.
There are now a number of different bolt action rifles, but almost ALL of them are simply variations on the Mauser design.
The Winchester Model 70 was very close, and the Remington Model 700 is a variation.
In your case, the Ruger was quite deliberately a fairly close copy of the original Mauser 1898 design.
Take a good look at the bolt design, the magazine and trigger guard assembly, the receiver design, and the extractor.
These are classic Mauser.
Compare your Ruger to almost any other bolt action rifle and you'll see that the same general theme is more or less repeated on the other rifles.
There will be differences, but the major idea of the locking system, bolt design, magazine and trigger guard, and attachment to the stock are just
variations on the same idea......Mauser.
