Parkerized model 15's
I was DOD Police at Otis ANGB, MA, from 1983-1989. About 1985-86 time frame, our police force was increased quite a bit, and therefore more model 15's were needed. I remember we received a crate straight from Warner Robbins AFB, GA, and inside were about a dozen new parkerized model 15's. Target hammer, target triggers, magna stocks, and USAF stamped as I recall. They looked brand new. I was issued one because my older, blued S&W M15 was suffering from "push-off" from a cocked hammer and the unit armorer pulled it from me for repair and issued me one of the parkerized guns.
