The RT-20 had been successfully deployed during the war in the former Yugoslavia in the second half of the 1990s. It  is manufacture by the Croatian company RH in the Croatia in the mid-1990s as a pure anti-materiel and anti means "Rucni Top, 20mm", that  is  "Hand Canon, 20mm".  It  is one of the most powerful anti the only others design roughly comparable to this monster in the terms of the caliber and  NTW-20  rifle and  the Finnish Helenius APH-20  (will be posted at  this site  later).  20 had been successfully deployed during the war in the former Yugoslavia in the second half of the 1990s.

The RT-20 name  means "Rucni Top, 20mm", that  is "Hand Canon, 20mm".  It  is one of  the most powerful anti-materiel rifles  fielded by  design roughly comparable to this monster in the terms of the caliber and 20  (will be posted at  this site  later). 20 had been successfully deployed during the war in the former Yugoslavia in the second half of the 1990s. It is manufacture by the Croatian company RH-Alan and is officially adopted by Croatian army.

The RT-20  is built around  the very powerful 20mm ammunition, originally developed  for Hispano Suiza HS404 anti aircraft  round of WW2 vintage. This ammunition  is still used  in anti generally available in HE (explosive) and AP (anti also can be successfully used against infantry fighting vehicles and armored personnel carriers. The 20x110mm round fires  the  130  gram  (2000  grains)  projectile  at muzzle  velocities  about  850 meters  per  second.  This  results  in  high  terminal  effectiveness  but  also  imposes  a  serious  problem  of  excessive  recoil  forces.  The  20mm  Hispano  round  generates about 4 times more recoil when fired fr10kg  rifle  (such  as  Barrett M95).  

To make  the  recoil more  or  less  bearable  by  the  average  shooter,  the Croatian designers developed a quite interesting counter large reactive tube, located above the barrel. The forward end of this tube is connected to the barrel at about its middle point. The rear part of the tube forms the reactive nozzle. When gun is fired, some hot powder gases are fed from the  barrel to the reactive tube and back, forming a back muzzle brake further helps to decrease the recoil.

The system consist of the large reactive tube, located above the barrel. The forward end of this tube is connected to the barrel at about its middle  the reactive nozzle.
