They should add this and the S18/100 to tech tree, move all semi-auto AT rifle to BR1 and apply the same nerf as Solothurn S18/100 has to all semi-auto AT rifle so there would be an incentive to use bolt-action AT too.
During the occupation, the development of anti-tank rifles at Zbrojovka Brno was not limited to single-shot and repeating rifles. In February 1941, the designer Josef Koucký (11 March 1904-25 July 1989) developed a self-loading variant of the ZK 407 in 7.92 x 94 mm calibre (German Patrone 318 cartridge) with a detachable five-round magazine and a drum magazine with double capacity. During March the armoury produced all the components and in early April informative firing took place with the first, but also the only example produced. During further tests in May 1941, it became apparent that the gun operated reliably with only four rounds in the magazine, and the high pressure at the point of gas pressure extraction from the barrel disproportionately increased the velocity of the bolt mechanism. After a number of modifications, the weapon did show reliable operation during tests in August 1941, but further development was abandoned.
The only produced example with the number 0101 was acquired by the Military Historical Institute in 1994 by transfer from Prototypy, a. s. Brno.
