the TzL-12S Metla (Russian for broom) it's a simple cheap and efficent break action survival rifle, the firearm is made out of steel, barrels firing mechanism and such, while most of the body is made out of high strength impact resistant polymers, the firearm have interchangeable barrels that allow to use a vast amount of different calibers usually arranged with a top rifled barrel for usually a rifle round like .223, 5,45x39 or .22 LR and the lower one a smooth barrel for .12 or .20 gauge, inside the stock there's a modular space to hold rifled barrel rounds while on the sides of the barrel there are two water proof tubes to store the shells for the smooth bore or some survival equipment if needed, the left one also have an integrated flashlight ideal to illuminate target having both pulse and toggle buttons.
The firing mechanism is a rather easy single action that can be operated even if the extreme trigger breaks down, components are bulky and robust making this an easy long lived weapon easy in all it's aspects even aiming in fact thanks to the fiber optic sights get a prefect shot is no problem in any light condition
