Operating by means of unlocked blowback and firing from the closed-bolt position, the KEDR family of submachine guns have a 1 mm-thick stamped sheet-metal receiver that features pinned, riveted and welded construction. This is a very compact and lightweight design. Production series specimens carry a black phosphate finish.
Weight of the KEDR, empty is only 1,4 kg (about 3,1 pounds). The KLIN is just slightly more. This is somewhat lighter than even the Czech Scorpion. With the stock folder, the overal lenght of KEDR is just 303 mm (about 12 inches). With the stock extender, the lenght increases to only 540 mm (21,26 inches). The KLIN is 2 mm longer. Cyclic rates of fire are 800 to 850 rpm with standard 9x18 Makarov ammunition and 1,030 to 1,200 rpm when high-impulse Makarov ammunition is fired in the KLIN SMG.
The barrel for both weapons is 120 mm (4,7 inches) in length. The bore has four grooves with a right-hand twist of one turn in 240 mm (9,45 inches). The KLIN barrel has been moved forward in the receiver 2 mm so that the feed ramp and receiver body could be altered to provide releable feeding of the high-impulse cartrige's truncated cone bullet
The buttplate, a machined forging, is welded to to the stamped sheet-metal stock.
The stamped sheet-metal trigger guard has been welded to the receiver at the front and rear. Equipped with a pivoting locking bar, the stamped sheet-metal receiver top-cover has a forward cutout on the right side for the ejection port.
A machined drop-forging, the bolt body has an integral cocking piece on the left side. Its floating firing pin has no spring. There is a spring-loaded claw extractor on the preechface. The fixed ejector is pinned in place on the left receiver wall. The bolt receprocates on rails inside the receiver. Two sets of cut-puts in the receiver rails at the rear permit removal of the bolt group during disassembly.
There is a single-coil recoil spring and conventional guide rod. The rear and of the guide rod is attached to a plate with a pin that enters a hole on the rear of the bolt body when the bolt reaches the end of its recoil stroke. This prevents the bolt group from jumping off the rails because of the disassembly cutouts at the rear.
The front end of the trigger mechanism is held in place by the selector level shaft, which also has a trigger block on it. A protrusion on the selector shaft activates the spring-loaded bolt hold-open after the last shot has been fired. In the safe position, the bolt hold-open pin also locks the bolt in the forward position. Cyrillic selector markings on the receiver are, from top to bottom: "AB" for full-auto, "OD" for semi-auto and the character pi and "P" (the letter R in english) for safe. This is not the same sequence used with the AK series, which is, top to bottom: safe, semi-auto, full-auto
