I have three .308 rifles. No case extractor at all. Rifles are; Remington 788 bolt action, H&K SL-7 (internals very similiar to G-3), and AR-10 by DPMS. Obviously as a prepper I should have proper tools for my MBR's ..... the autoloaders. I would like to have one good case extractor that will work on all if possible. Will gladly accept advice on needed tools for AR-10 platform or H&K Thanks in advance for any good suggestions.
