I can pick-up a Rem. XR-100 rifle in .308 for cheap. I would like to build a Palma rifle from the solid bottom, single action. My questions are: Is this a decent action for this project, or am I better off w/ something else? Are there stocks available, w/ rails for hand stops, for this action? Are the Williams or Lyman rear sights ,sold by Brownells, useful for match shooting, or are they complete junk? Any knowledgeable answers would be greatly appreciated... Thanx in advance
