 | | Although the M16 Rifle and the M14 Rifle are not comparable in design, weight, ballistic parameters, operating features and effectiveness, their reliability characteristics are approximately similar. |

 | | The primer mixture, the primer weight, and the conditioning temperature of the ammunition were varied to investigate their effects, individually and in conjunction with each other, on the cyclic rate of the M16 rifle, on the action time of the ammunition in the rifle, and on the velocity of the projectile. |
