U.S. Model 1892 receiver views

Post by butlersrangers »

This nice early 'stripped' receiver just sold on GunBroker.

The photos give a good view of the details of an early Krag receiver.

Beautiful reciever! The quality of the work is remarkable. In the picture of the front of the receiver, what is the vertical slot in the receiver ring? Sincerely. bruce.

That is a very clear Index Mark. A similar line is on the Krag barrel, to insure proper barrel location (indexing).

Krag barrels were completely finished before installation on a completely finished receiver.

Thank you for the kind reply. From the photo it looked like a slot cut into the metal. Did not realize it was a witness mark.

Given that the Krag barrel was completely finished before installation, would that mean that the chamber was completely chambered and finished with no further steps required?

Was this degree of finishing carried over to the 1903 so that barrels did not require any final fitting when installed? Sincerely. bruce.

'ebruce' - That index mark on the early model 1892 receiver does look a bit like a cut slot.

Later Krags generally have more discrete index marks, just on the front edge of the receiver and a light line on the barrel.

'ebruce' - My understanding is that Krag barrels were completely chambered before installation on a receiver.

All the barrel elements that had to 'clock' properly with the receiver, (the threads, the index mark, the extractor notch, rear-sight screw holes and front-sight base), were completed during barrel manufacture and prior to 'browning' (rust bluing).
The finished barrel met its finished receiver randomly, yet indexed properly.
The flat-face of the Krag barrel breech and the fact that headspace was simple and related to cartridge flange/rim thickness, likely made this barrel-fit relatively easy.

The 1903 Springfield barrel with its 'coned' breech and the head-space for the rimless .30-06 cartridge, being to a datum-line at the case shoulder, presented more of a problem.
I believe the 'mostly' finished 1903 barrel was installed on the receiver, but then required finish reaming of the chamber for proper headspace at the shoulder.
