      Can those with Ruger #1 rifles please post the barrel contour measurements, please.
      On another topic, I am building a Woodland Safari carbine, small ring mauser.
      I been shopping for quarter rib, and banded front sight ramp base. Both of these seem pricey, and a custom job.
      that is, until I found Ruger parts at Brownells. here is the link I found
      http://www.brownells.com/search/inde…+rib&ksubmit=y
      http://www.brownells.com/search/inde…ront&ksubmit=y
      Can those with a Ruger #1 post the dimensions such that a part number sight base can be matched to a contour and selected to fit common sportier barrels like Shilen, Douglas, etc.
      There is Ruger #1H, #1S, #1A, #1B and so on.
      Thanks for your help.

      Thanks, thats interesting.
      It still doesn’t tell me the diameter under the Ruger #1 qtr rib, though.
      I did call Brownells, and they can get me the info from a drawing. They have to look that up the old fashion way, from paper drawings.
      Has anybody noticed that from that link you posted, I looked at Lilja barrels in stock, and they show a .308 SS 1/14 twist Rugermag contour.
      That is a discounted price, and should make a dandy XCB barrel.
