7.92 mm M SS 41: Antitank Rifle

7.92 mm M SS 41: German WW2 Antitank Rifle

This antitank weapon, a manually operated, magazine-fed, air-cooled, high-velocity rifle which was standardized for production in 1941, fires the same necked-down cartridge as the Panzerbüchse 39. Although classified as an antitank rifle, the use of heavier armor on modern tanks has rendered the weapon effective against lightly-armored vehicles only.

A hinged bipod similar to that of the MG 34 is attached to the front of the receiver jacket. It folds forward for convenience in carrying. The gun is also equipped With carrying handle and sling; the former is fitted to the top of the barrel group, and the latter is attached on the right side at the bipod and back plate assembly.

A “U” type rear sight and an adjustable front sight of the square block type fold to the rear when not in use.

The gun is put in a “Safe” position by pulling the barrel housing lock extension 1/4-inch to the rear so that its rear alignment mark is aligned with the mark “S” on the barrel housing lock. When in this position, the trigger cannot be pulled, nor can the action be opened. If the trigger is pulled while the action is not entirely closed, the gun will not fire. It is necessary to release the trigger and pull it again in order to release the sear. When the magazine is empty, the action is kept open by the protrusion of the magazine follower which stops the rearward movement of the barrel housing.

7.92 mm PzB 35 (p): Antitank Rifle (Ex-Polish)

7.92 mm PzB 35 (p): Antitank Rifle (Ex-Polish)

During the Polish invasion, the Germans captured large numbers of the Mascerzek Model 35, 7.92 mm antitank rifle. These were used extensively in the earlier part of the war.

This Polish rifle is a weapon similar in design to a Mauser rifle firing a normal cartridge, but it is longer and heavier, and a muzzle brake has been attached. It led to the development of the German rifles, known as the Pz. B. 38 and Pz. B. 39.

This weapon is a bolt-action gun of the modified Mauser type and has a detachable box magazine. It is carried by a sling attached in the usual manner. It may be recharged with ammunition by exchanging the magazine or by reloading the empty magazine with single rounds. The body is a hollow cylinder with an ejection and loading aperature on top and a magazine slot at the bottom. The bolt is cylindrical with a straight lever at right angles on the right side (in the closed position).

The barrel, which is parallel throughout most of its length, increases in diameter toward the breech until it equals that of the body. At the muzzle, a portion is threaded to take a muzzle brake. The bipod is of light construction and is attached to the barrel by a yoke. The legs of the bipod terminate in circular shoes which are cut away on the inside to clasp the barrel when they are folded forward in a closed position. The magazine is of the box type.

SPECIFICATIONS

Caliber         7.92 mm (.312 in.)
Weight 20 lb. (approx.)
Length 5 ft., 10 ins.
Ammunition Steel jacket with A.P. steel core and lead antimony filler
Sights Rear, fixed; front, adjustable blade
Capacity 5 rds., in clips
Muzzle velocity 4,100 f/s

7.92 mm Panzerbuchse 39 (Pz. B. 39): Antitank Rifle

7.92 mm Panzerbuchse 39 (Pz. B. 39): Antitank Rifle

The German antitank rifle, Pz. B 39, 7.92 mm, is a weapon of opportunity which is used by the German Army against vehicles having light and medium armor. It fires a cartridge similar to that used in the Polish Mascerzek antitank rifle. This cartridge also resembles the American .50/.30 which has been under development in this country since 1931.

The projectile has a tungsten carbide core and is known to have a small pellet of a lachrymator as well as a tracer mixture. Penetrating power of the bullet at 300 yards’ range is 3/4 inch at 20°, and 1 inch at normal against face-hardened plate. At 100 yards’ range, penetration is 1 1/4 inches at normal.

The weapon has proved to be a simple and reliable gun. The recoil is comparatively light. The rifle is manually loaded and fired single shot from the shoulder with the aid of a bipod. It is equipped with a circular turbine muzzle brake.

The Germans also have an earlier version of this weapon known as the Pz. B 38 which is 7 pounds heavier, has a self-ejecting action, and is more elaborate than the hand-operated Pz. B 39. It fires the same ammunition as the more recent rifle.

The Pz. B 39 uses ammunition boxes holding 10 rounds each, mounted on brackets on each side of the wood stock. These are not magazines but serve to hold the ammunition so that it can be quickly and easily removed for hand loading.

Weight 27.25 lb.
Length (with shoulder stock extended) 62.25 ins.
