Crafted to perfection, the Adjustable LCK-19 (Pk-410) flask is an ergonomic flask inspired by the design of the AK-12M carbine. Made primarily with long-lasting plastic, the flask also features a rubber foot with an anti-slip texture. With 6 adjustable length positions and 7 height positions on the foot, this flask can be tailored to the shooter's specific size and aiming height. Included in the package are the flask itself and mounting screws, making it a versatile addition to any replica fixed-barrel carbine like the AKM or AK-74.
