You guys crack me up! I actual qualified expert in 78 at lackland basic with a AR 15 in.22 cal. Did I mention it was January the temp 15 degrees wind chill. Oh did I forget to mentiion at the time I had only fired a BB gun up to that point. That .22
Made me look good so I see why they would use them.

I wonder what they did with all those Milsurps when the USAF were done with them?
