Panzerbuchse 39 anti-tank gun (PzB 39)
In the second half of the 1930s design engineer B. Brower (B. Brauer) German company «Gustloff Werke» has developed a single-shot anti-tank gun, which in 1938, with the designation «Panzerbuchse 38" (abbreviated «PzB 38") was adopted by the army in Germany. The basis for this was laid weapons specially designed for anti-tank rifle cartridge "rifle" caliber 7.92 mm with a sleeve of high volume, known as «Patrone 318».
Loading the PTR PzB 39
very first combat use RzV PTR 38 in the Polish campaign in 1939 revealed its many shortcomings: first large mass and bulky size. In addition, numerous complaints caused unreliability of weapons, including - frequent failures as the fault is not entirely spent locking system, and in terms of pollution. Furthermore, although a method for forming metal, the production of these weapons require a considerable amount of material and means.
After numerous complaints
B. Brower was forced to radically alter gun RzV 38. At the same time it greatly simplify the design and reduce the cost of production of these weapons. The new anti-tank gun received index «Panzerbuchse 39" (abbreviated «PzB 39") and was accepted into service of the German army at the end of 1939.

7.92 mm anti-tank gun RzV Z9 also use cartridge «Patrone 318" that was meant to deal with light tanks and armored personnel carriers of the enemy at ranges up to 300 - 400 m, different from its predecessor, less weight and size, making it is virtually equivalent maneuverability hand guns. Appearance of new weapons like the previous model, but the principle of operation has been modified (movable barrel and semi-automatic slide catch were abolished. To stop now used vertical shutter delay. However shutter had no self-opening and self-automation ejection.).

antitank rifle PzB consisted of 39 main parts, components and mechanisms: the barrel to the receiver, trigger frame with handle reloading; shutter; folding butt, the bipod and two stores accelerators.
From a technical standpoint PzB PTR is 39 singly charged gun, semi-automatic vertical wedges. Reloading shutter is the trigger lever.
With the loading rifle shooter movement (away from you) pistol grip fire control opens the shutter, the other hand took out the cartridge from the magazine and laid it in the chamber. Thereafter, the pressure on the pistol grip (to the shooter), the shutter closes and the gun was ready to fight. After the shot sleeve is extracted with lowering the shutter slider extractor back down through the window in the shoulder rest.
muzzle brake and front sight PTR PzB 39
To prolong the life of the shutter had a removable front insert allows for minimal gap between the mirror and shutter a treasury muzzle.
Top flap valve closed automatically casts when lowering the shutter.
hammer type firing mechanism. Cocking lever when lowering the shutter.
lever type fuse located at the rear of the receiver, behind the jack plug (at the left of his position and the shutter locks sears). Protection from premature snap shot carried the pistol grip fire control, whose projection trigger lock when not fully closed the barrel.
trunk, tapering toward the muzzle, was mounted on the bed motionless arms. To reduce recoil when firing on the trunk fastened powerful muzzle brake that absorbs up to 60% of the recoil energy.
Fixed sight, strut-type, was calculated on the firing range of up to 400 m Fly defended ring guard.

10-charging ammunition box accelerator
To improve practical rate of weapons used in two 10-cartridge box chargers boosters, crepes on both sides of arms.
Butt PzB PTR 39 in the retracted position
To reduce the size in the stowed position and reduce recoil gun had a folding metal stock with a pillow protectors. Folding down the butt-forward, is pivotally attached to the receiver and hold the latch.
For stabilization when shooting and reduce the size of the gun in the stowed position, the trunk was fixed at two-legged folding bipod structurally similar bipod MG P4.
served flip sideways handle mounted on top of the center of gravity weapons.
weapons consisted of two people - arrow and podnoschika ammunition (aka watching purpose). On the march vozilos gun with ammunition in the wagon. For transportation of guns in the intelligence divisions of infantry used bicycles, frames which belts fastened PTR. In combat conditions endured payment gun on the shoulder or in your hands. In the vicinity of the enemy's rifle carried by one shooter.
PTR PzB 39
Despite the relatively low muzzle energy of the bullet Patrone 318 MFR PzB 39 at the time was relatively high combat qualities, punching armor thickness of 30 mm at a range of 200 meters (at 90 °) and 20 mm at a distance of 400 meters (at 20 °).

When using the
fighting qualities of these anti-tank rifles, which they showed in the initial phase of World War II forced the German military industry expand its widespread manufacture. In 1940-1941 the company Gustloff-Werke, Rheinmetall-Borsig, Havelwerke, Steyr-Daimler-Puch fired antitank guns 39232 RzV Z9.

By the time
Panzerbuchse MFR 39 (PzB 39) was the main weapon of the German infantry antitank defense. Each infantry platoon had 1 MFR, in the company - 3 pcs., Battalion - 9 pcs., The regiment - 27 pcs. Just Infantry Division's remained in the 90 anti-tank rifles. In motorized division there were - 83 pcs., And tank - 57 pcs. In 1941, in the infantry, motorized infantry and mining engineer-sapper battalions had one branch with three anti-tank guns PzB 39. One SSS had in motorcycle platoons and 11 reconnaissance company of motorized division.
However, along with the successful design solutions, these weapons and had many shortcomings. To the negative traits include the difficulty in manufacturing, debugging and learning. Particularly complicated system were reloading and firing mechanism, consisting of 63 items. In general, the gun turned out to be unreliable in difficult operating conditions due to their sensitivity to pollution. In addition, large enough to bring a claim to tight extraction cartridge cases when the arrow had to put considerable effort to unlock the trigger frame.

In general, anti-tank guns were used in 39 PzB fairly limited scale as in the French campaign of 1940, and slightly more than in 1941-1942 on the Eastern Front, where quite successfully applied mainly against lightly armored targets. In the summer of 1941 the German infantry had to deal with the Soviet tanks T-34 and KV against which the weapon was ineffective. Heavy fighting, which had to fight the German infantry during the Soviet offensive near Moscow winter of 1941-1942, showed that the entire system of antitank defense was practically inactive. Anti-tank guns, which were in service with the Wehrmacht did not meet the requirements of the time. Fighting on a par with medium and heavy enemy tanks with thick armor 60 - 90 mm could be conducted only more powerful weapons.
