M16A1 M203 (download)

The M16A1 is an automatic assault rifle which replaced the M14 rifle to become the US military's standard service rifle during the Vietnam War. The original M16 fared poorly in the jungles of Vietnam and was infamous for reliability problems in the harsh environment. The M203 is a single-shot 40 mm under-barrel grenade launcher designed to attach to a rifle. It uses the same rounds as the older stand-alone M79 grenade launcher.

M16A1是一款自动突击步枪，在越南战争期间取代M14步枪，成为美国军方的标准制式军用步枪。初代M16在越南丛林中表现欠佳，因在严苛环境下暴露出可靠性问题而声名狼藉。M203是一款单发40毫米下挂式榴弹发射器，专为加装于步枪而设计，其所用弹药与老式独立式M79榴弹发射器相同。FBX源文件来源：Objaverse 1.0 / Sketchfab
