Granatomotny complex “showcase” with a grenade “showcase – D”
"Showcase-G" collected during the fluoroplastic body and filled with a liquid solution of irritant chloroacetophenone.(CN).This tear gas during evaporation or in the form of an aerosol having an impact on sensory nerve endings of the eyes and upper respiratory tract, It is causing a burning sensation and pain in the eyes and chest, lacrimation, provokes a runny nose and cough. Besides, of the grenade includes a shank, made of metal and cylindrical type stabilizer, made of plastic. Upon meeting with an obstacle lifting charge exploded instantaneous form aerosols chloroacetophenone CN.
To mitigate the restoring force when firing from a grenade launcher on the butt worn recoil pad – absorber "colossus", It is fired from 40 mm "podstvolʹnika" GP-25 "Koster". Grenade launcher "Showcase" has long been used divisions of KGB special forces and was commander of the armed “Alpha” during a special operation of various kinds.
Using granatomotnogo "Showcase" of the complex in a number of special operations identified a number of major shortcomings. The main of them were strong recoil and low aiming at a distance 70 m, explained that a small initial velocity grenade 65 m / s. Large caliber grenade led to, that the strength of the impact was considerable, even for people used to the special loads Special Forces soldiers with the shooting from the grenade launcher. For a shot butt AKS-?4I had to rest against the ground, and about any accurate shooting at a target is not mentioned. Grenade launcher "Showcase" became the prototype of the hand grenade CSG-50.
