KBP PP-90M1.

PP-90M1 is a conventional blowback operated, selective fired machine gun. The gun housing is made entirely from plastic, including integral pistol handle and trigger guard. The top-folding buttstock is made from stamped steel. Safety / fire mode selector is located at the left side of the gun, above the trigger. An original layout makes the weapon very compact. A screw-type cylindrical magazine placed horizontally under the barrel serves as a foregrip without increasing the gun dimensions. Wide employment of composite plastics reduces the weight of the weapon. Optimum rate of fire (600 rds./min) facilitates ammunition expenditure control and contributes to better accuracy and efficiency of automatic fire. The weapon is distinguished by high accuracy in single fire mode. A 64-round magazine allows keeping on firing until inevitable stop for reloading longer than the enemy. The advantage of this design is the possibility to store loaded magazines for unlimited period. The PP-90M1 is strong enough to routinely fire powerful Russian-made 9x19mm ammo with armour piercing bullets, 7N21 and 7N31, which is about 9mm +P+ or even +P++ class in the terms of barrel pressure. Any military or commercial 9x19mm ammo can be fired from PP-90M1 safely as well.
