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.

This is effective at distances of up to only 450 metres; beyond this, the delay continues to increase, but at a rate too small for humans to distinguish ...

Farrington in 1878, while a rarer type of the clip now known as Swiss-type (after the Schmidt–Rubin) frame charger was patented in 1886 by Louis P. Diss of Remington Arms. [3]
