  1. Slammed bolt on headspace gauge

    Gunsmithing
    Band new M1A scout, not one round through it yet. To make an embarrassing story short, due to inexperience, I released the bolt (wasn’t stripped either) and it slammed home on a forester field gauge and went into battery. How screwed am I?

  5. I'm still confused on headspace...please help

    The M14

  6. Question about headspace

    The M14
