    In 1930 Japanese gunsmiths began work on the development of anti-tank rifle. And by the second half of the 30s, based on the construction of 20-mm aircraft cannon, the original sample was created autoloading heavy anti-tank rifle.

    In 1937, it was adopted into service MFR Japanese Army Corps under the designation «Type 97" (97 - year adopting. 1937 of the Gregorian calendar year 2597 was the traditional Japanese calendar). In some sources this weapon known as "Chiana Shiki».

Equipment for these bezrantovyh cartridges used several types of shells, which were equipped with one or two copper driving bands. Most commonly used standard armor-piercing shell which meet at an angle of 90 ° at a distance of 250 meters past the armor thickness of 30 mm. Also used tracer, shrapnel and high-explosive projectiles, allowing use as a weapon PTR support. Armor-piercing projectile weight was 159.4 grams, the weight of the powder charge a little more than 20 grams, the initial speed was 950 m / s, and the muzzle energy of 59.6 kJ.

    Type 97 anti-tank gun consisted of the barrel, receiver, mobile system comprising a bolt carrier, bolt and locking wedge recoil device, trigger, machine-cradle.

    Automation weapons operated by removal of powder gases located under the barrel with two gas pistons. For locking wedge raised upward by the bevel on the bolt carrier and bolt pin to the receiver. After a shot under the influence of the gas piston bolt carrier began to retreat and bevels lowered wedge, opening the shutter. Shooting was conducted with an open shutter.

    cocking handle is situated on the left side of MFR.

    To reduce the impact on the trunk was attached muzzle brake reactive action, and the barrel to the receiver had the ability to roll back against the housing arms, clutching recoil spring buffer.

    the rear of the receiver is a lever type fuse with a stopper.

    Food SSS ammunition made from detachable box magazine capacity of 7 rounds, connected at the top weapons. Receiving a shop window in the stowed position to protect against contamination of parts and mechanisms receiver closing a flap.

    Sights, consisting of flies and racks with sight glass, left handed on the brackets that attach to the cradle. Mechanical sight adjustable, with settings for the range from 100 to 1000 meters. There was also the possibility of installing an optical sight.

    weapons are placed on the bipod, secured in front of the machine-cradle. For additional support and fixing weapons in a certain position at the rear of the machine-mounted cradle was an additional flip stop. Bipod and rear stop adjustable in height, their position was recorded locking sleeves.

    the rear of the machine is the cradle-shoulder rest with Shoulders.


    MFR was designed removable shield which are generally unused.

    In machine-slot cradle were joining two tubular handles for carrying: front and rear. With these arms gun battle was transferred to three or four soldiers. In the stowed position the gun was transported in a special hand-bogie.

    Type 97 anti-tank gun could fire bursts, but it showed too low accuracy. Another major drawback was the payoff. Recoil device, even in conjunction with a powerful muzzle brake, which snuffed out 60% of the recoil force, in practice proved to be ineffective. Because of the strong impact of the Japanese anti-tank riflemen were cases of fracture of the clavicle. Weapons also had considerable weight, which with a full magazine and a removable shield reached 68 kg. On the battlefield, the gun was transferred to the hands using special pens, and even though the payment of arms consisted of two people - arrow and podnoschika ammunition for carrying it usually took three men and a fourth transfer ammunition, which greatly complicated the shift position in a real combat situation. MFR was good on stable position, but the maneuver fire along the front was difficult. Unwieldy weapon was used mainly in defense. Calculations preferred to work on a pre-prepared positions and adjust points boundaries.
