There are many others on this Forum who are much more knowledgeable than I and can help you with this/these problems but my guess is that you probably need a new Butt stock. These are somewhat eccentric rifles with bedding requirements quite different than other bolt action rifles. In regard to the rear sights: I believe you have a couple of options from a military micrometer sight with elevation only adjustments to a full bore Parker Hale target sight with both elevation and windage adjustment, expensive, ($200 plus, but worth every penny). There is a windage/elevation adjustable sight available from Sarco. This is a sight originally intended for a .22 rifle and does require the enlargement of the action mounting hole. Hope this helps a little.
