'Agent68' - Welcome to the KCA Forum!

Your Right or My Left? It's all about orientation.

Actually, the Krag's magazine 'Cut-Off' switch is located on the Left-Side of the receiver. The side that has the U.S. Model 1898/ Springfield Armory/and serial number marking.

The sights that require the removal of the 'Cut-Off' are the Pacific (K1 & K2) and the Redfield (K-102 & K-75). These sights require no new tapped holes, since they use original Krag machined holes and surfaces for mounting. These sights mount on the left-side of the Krag action and use the hole of the removed 'cut-off'.

There are other Krag 'after-market' receiver sights that mounted on the left-side and some on the right-side of the receiver and required new tapped holes. These did not require Cut-Off removal.

The Krag 'cut-off' has a 'flat' area on its shaft. It works by allowing cartridges to feed up to the bolt area from the magazine, when the 'flat' is properly oriented in the receiver side-wall. When the round part of the shaft is exposed, it blocks cartridges from feeding.

If you are loading several cartridges into your magazine and the bolt picks up and feeds the first cartridge, the feed-path is clear. The problem likely has nothing to do with the Magazine Cut-Off or its absence.

If the above is the situation, then the failure is likely a problem with the follower/follower-arm assembly. This could be caused by dried grease and crud, a damaged side-plate, wrong model parts, or a broken or weakened (magazine-door/follower-arm) spring.

Detailed (clear-closeup) photos of your Krag's action could allow better diagnosis.

Taking off your Krag's left side-plate allows examination and testing of feed system components. (This normally requires the barreled-action to be removed from the stock).

Attached photo shows 'flat' tip of model 1898 Cut-Off shaft in the cartridge 'feed' position.
If the Cut-Off Lever was turned 'down', a round portion of the shaft becomes visible, blocking cartridge feed.
