I had two Ruger No. 1's rebarreled.
They were originally 1A's, and I had NECG peep sights for them which fit on the Ruger scope mounts.
I thought long and hard, and decided that the importance of accuracy with a single shot rifle outweighed appearance.
I had the gunsmith keep the short barrel of the 1A, but add a tapered forend, long enough for a sling swivel. Sort of a 1AB but without iron sights.
And they have Zeiss 3-9X40 scopes.
Kind of funny-looking, but they shoot...
