Having used a Pacific sight years ago on a Krag sporter, I can attest to its efficiency. Removing it periodically to give the bore a good cleaning was never an issue. So what if I had to re-sight in? "Darn it, now I have to go the range again!"
The Rice sight is intriguing but I like to swap out apertures (or use a Merit disc) to meet the challenges of different lighting. The sight pictured here (which I'll guess is craftsman made) negates that with its screw-in aperture.
Like Michael, I would opt for a Lyman 103 cocking knob sight too- if price were no object. As it were, the sight I opted for on my current Krag project is a NIB Lyman 48.
