Ha! Did the same thing (Basic, not Boot & AIT, not ITR) circa 1969-70We went from M14 in boot camp to M16 in ITR...I was disgusted...loved the M14. Didn't like the 3-pos safety...wasn't aware they'd changed it...makes sense to me. I liked the Mini-14 because of the M14- type safety.
Let two get away from me .
Well, there goes your days of dragging your AR on the ground.I picked up a safety at the Wannamaker show several years ago that slips right in, it is vertical when safe then just thumb the lever forward to fire. I dropped white and red paint to make the markings read correctly.
