Stripper clip
A stripper clip (also known as a charger or charger clip, especially in Commonwealth English military vocabulary) is a speedloader that holds several cartridges (usually between 5 and 10) together in a single unit for easier and faster loading of a firearm magazine. Stripper clips were originally utilized in infantry bolt-action rifles, such as the Russian Mosin–Nagant, the British Lee–Enfield, and the German Mauser Model 1889, Gewehr 98, and its variant the Karabiner 98k, the Mauser action related American M1903 Springfield and M1917 Enfield, Swiss K31, and many others.
