The M196 tracer cartridge (54-grain bullet) 5.56×45mm NATO was developed for the original M16 rifle and is compatible with the M16A1 barrel also using 1:12 rifling twist. It has a red tip and is designed to trace out to 500 yards, and its trajectory matches the M193 (56-grain) ball cartridge, which has no tip color.

The projectile may be powered or un-powered, guided or unguided, spin or fin stabilized, flying ...
The B Mark VI incendiary bullet was packed with nitrocellulose, and a small steel ball was placed in the tip of the bullet to ensure that the chemical exploded on impact. As opposed to earlier designs, the B Mark VI was a true incendiary rather than tracer ammunition . [ 6 ]
