I have a Redfield no drill receiver sight (#70 I believe) on one of my Krag Sporters. The magazine cut-off will have to be modified in order to fit sight and have rounds feed properly. Many folks simply removed the mag cut-off when fitting the sight. The cut-off needs to remain in the rifle else the nose of most soft point cartridges will hang on chamber ramp step while trying to feed. The cut-off tip gives The cartridge the little lift it needs to clear over the step.

"Come, shall we go and kill us venison?
And yet it irks me the poor dappled fools,
Being native burghers of this desert city,
Should in their own confines with forked heads
Have their round haunches gored."
