ABSTRACT:
A slidable pin, in a gun breech bolt, impinges on a chambered cartridge sliding rearwardly, striking the arm of a pivoted angle indicator raising an indicator surface above the bolt in view of the user. A spring detent normally holds the pin forwardly so as to not strike the indicator when no cartridge is in the chamber.
