M-16A & M-16A2

Standard US military rifle since the 1960's, the M-16 has high accuracy and a staggering ROF. A built in "tumble" effect compensates for the light 5.56 round. Earlier M-16 models were cantankerous and unreliable in the extreme, with an accuracy of 1, not 2. The Ar-15 and the AR-180 are civilian models used by police and home defense.
