Interesting, but the terms of the explanation was a bit foggy.

The spacer serves to keep the bolt from being shoved too far up and to the left (looking from the rear) as it's driven by the slide and bolt lug forces. Not a problem if a cartridge is in the bolt face and centering everything but if closing the bolt on an empty chamber the bolt can be driven to high and left and become stuck a bit.

No, the spacer serves to prevent the barrel from being screwed too far into the receiver. The bolt should not impinge directly against the breech face. Without a cartridge in the chamber, the bolt should have a little bit of movement.

Some later commercial carbines did away with the spacer altogether. Really not needed.

If you go onto Jim Mock's site, it states that the reason for the barrel skirt is to help deflect the bullet in to the chamber. Also, it's been mentioned on some sites that it was meant to help protect the threads during installation.

I have carbines with dresses and commercial carbines undressed. Never have had a failure to feed with any of them.
