Can I put a .308 barrel on my M70 in place of the 300WSM? If so is it a direct swap and will the factory blind mag etc. work? Any replies appreciated. Thanks.

    You can put the 308 barrel if its properly chambered,but the 300wsm bolt is a magnum the 308 bolt fasce isnt as big as the 300wsm.if you have an extra bolt youll be right into 308 otherwise need to buy a 308 bolt.

    To summarize, you will have to modify:

    1. Bolt face (Best to find a .473 bolt and replace.)
    2. Extractor
    3. Feed rails, you will most likely have to use a detachable magazine.

    Hope this helps
