AR-15 Acronyms A
A1 - Of or referring to a characteristic of the M16A1 (for example, an A1 rear sight)
A2 - Of or referring to a characteristic of the M16A2 (for example, an A2 flash hider)
A3 - Of or referring to a characteristic of the M16A3, or (in civilian parlance) a flat-top receiver. Note that the M16A3 is essentially just a full-auto M16A2, but civilian manufacturers began using the term A3 for flat-top receivers before the military adopted the M16A3 and M16A4, so there is divergence between military and civilian usage of the term "A3". Without a definitive military context, it is most likely that "A3" refers to a flat-top, civilian upper receiver. Note also that some civilian manufacturers call their flat-tops A3, others A4.
A4 - Of or referring to a characteristic of the M16A4 (for example, a flat-top A4 upper receiver)
