a role in the history of infantry anti-tank weapons melee Nazi Germany played gunsmiths development Czechoslovakia during World War II. After the occupation of Czechoslovakia by Germany in 1939 research and development (R & D) to create anti-tank rifles (MFR), Czechoslovak designers started before the war, were continued in conjunction with the German gunsmiths.
weapons specialists Academy SS «SS-Waffenakademie» Brno and Czech firms gunsmiths «Waffenwerke Brunn» (the name of the Czech group «Zbrojovka Brno» during the German occupation) was created 7.92-mm anti-tank gun magazine- W/7.92 under German cartridge 7.92 mm h94 (Patrone 318). In 1941 it was decided PTR adopted German Waffen SS troops with the designation «PzB M. SS 41 ».
Then it was developed and 15-caliber single-shot-mm anti-tank gun, received the Czechoslovak designation W/15. New SSS was designed for use with the Czech machine-gun cartridge 15x104 Brno from heavy machine gun ZB 60 and represents an increase and a slightly modified version of the gun W/7.92 (PzB M. SS 41), but in the form of singly charged.
According to some sources the gun was never released commercially. On the other - a small batch of these weapons was delivered to Italy. By the third data - is a small amount of MFR's remained in the German units «Waffen SS» under the symbol «PzB 42» (Panzerbuchse 42 - anti-tank gun model 1942).

PzB 42 rifle was made under the scheme «Bull-Pup» (an arrangement in which the locking mechanism is in the butt, the receiver is located behind the cartridges, and the box trigger, trigger guard and fire control handle ahead of the receiving window.)
Locking and unlocking the gate was carried out due to the movement of rolling barrel. Cartridges are inserted from below into the recess with a special feeder, then, using the handle reloading trunk turned to the right, and disconnected from the shutter cocking the hammer spring. When moving the barrel forward his discovery occurred when reverse movement - Chuck was a member of the chamber and the barrel when turning left - it happened locking gate. Weapons ready to fire, and in this state can be inserted into the next cartridge feeder. Ejection port occurred when moving the barrel forward.
firing mechanism - striker type. Trigger mechanism is mounted in the pistol grip.
Unlike PzB M. SS 41 with single chamber muzzle brake gated trunk PzB 42 stocked more efficient three-chamber muzzle brake, significantly reduces recoil.
mounted on the housing shoulder rest, in order to reduce the recoil force was equipped with a shock-absorbing cushion to the cheek.
In front of the lodge is a metal folding bipod.
Sights consisted of a strut-type front sight and folding sight. The sight was designed for fixed firing range - 300, 600 and 800 m, although the effective range does not exceed 300 m
When changing positions on the battlefield gun tolerated in carrying handle, and on the march arms fastened behind the arrow on the special device to carry with straps like a backpack.
Despite the much more powerful cartridge PTR PzB 42 had about the same combat characteristics, like PzB M. SS 41, probably because of what it has not been put into mass production.
