    main purpose of RT-20 is the fight against enemy vehicles, including light armored.

    for firing "hand cannon" - that stands for the full name of "Rucni Top", used 20-mm shells (20h110 mm), created in the mid-twentieth century, anti-aircraft guns Hispano Suiza HS 404. Such munitions presented in versions with high-explosive, anti-armor and armor-piercing incendiary shells. The mass of the projectile - 130 grams, the initial rate - about 850 m / s.

    When shooting from RT-20 (20 kg) projectile caliber 20h110 creates impact, four times the recoil when firing the 12.7-mm rifle (10 kg). To compensate for the extremely strong returns designers had to apply RT-20, along with a massive muzzle brake and shock absorbing pads on the shoulder rest, reactive compensation system recoil similar kind used in recoilless anti-tank guns. Around the middle of the length of the trunk in the RT-20 do a number of holes through which part of the barrel of powder gases diverted into a pipe extending above the barrel, and gases are vented her back, creating a reaction force opposing forces recoil. This system allows the use of ammunition, much superior to the power of projectiles that are used in other samples antimaterial rifles caliber 20 mm, such as NTW-20 (South Africa) and APH-20 (Finland).
