It appears, Captain Kivan believed the Krag sling, being anchored to a butt-swivel, instead of at the front of the trigger-guard, would pose problems with 'the manual of arms' and the wearing of a pack or haversack, (for extra socks and underwear).

How in 'Heaven's Name' are you going to carry a Rice Shelter-Half and a slung Krag?

Damn Foreign rifle!
