Gazyr

A gazyr (via Russian: газырь from Turkish hazır, "ready", ultimately from Arabic; Chechen: Бустамаш bustamash, Georgian: მასრები masrebi) is an implement to hold a rifle charge: a tube with a bullet and a measure of gunpowder or a paper cartridge. They were carried in gazyr bags or in rows of small pockets on the breast. Later, gazyr pockets became a distinctive element of national dress of the peoples of Caucasus, such as the chokha.[1]
