Soviet Union's First Generation 1PN34 Night Vision Scope Appears in Japanese Antique Gun Shop to Observe Distortion of Vision

recently, a Japanese antique gun store displayed a Soviet NSPU(1PN34) night vision scope.

This is the first-generation night vision scope developed by the Soviet Union, and it is also the NSPU series with the largest number of equipment and the most widely used model. In addition to the mirror body, this scope also has a canvas bag and an infrared filter cover. The exterior of the mirror body is painted in silver gray, which is very heavy due to the extensive use of metal materials.

NSPU is a passive infrared sight, which obtains a brighter night view by amplifying moonlight and starlight. The NSPU scope uses the Soviet standard side frame, so it can be installed on the Kalashnikov rifle and Dragonov sniper rifle (SVD). This photo seems to be the Soviet special forces during the Afghan War. They used AKM rifles equipped with NSPU night vision scopes, PBS-1 silencers, and grenade launchers under the GP-25 (worthy of elite hair, arms are really strong).

Since the firearms equipped by the Warsaw Pact countries use standard mounts, 1PN34 can also be installed on weapons manufactured by the Warsaw Pact countries. This is the staff mounting the 1PN34 to the Romanian AMP-69 rifle. Although the shape of the mount is slightly different from that of the Soviet Kalashnikov rifle, the lock is stable.

frame, which is written in English as NSPU, which is the abbreviation of "night shooting and aiming equipment. There is a sickle axe red star logo in the middle, indicating that it is made in the Soviet Union. It is presumed to be the product of the 69th instrument design factory in Krasnogorsk. There is an adjustment knob on the lower part of the center of the frame to adjust the brightness of the reticle. At the bottom is a locking lever, which is used to fix the scope on the mounting seat on the right side of the receiver.

1 PN34 is installed in the state of the lens cover. This lens cover is also made of phenolic resin, which is the same as the small grip and magazine material of the Kalashnikov rifle. The use of wear to make its surface coating fall off, revealing the unique brown-red color of the internal material, is it very AK magazine flavor? The lens cover is fixed with the front section of the scope by the bayonet, which is difficult to disassemble and assemble due to the deformation of the bayonet due to bumping.

, it should be noted that this objective cover is actually a filter, and the center is quite a dark lens. After installing the objective lens cover, the light entering the scope can be reduced to prevent damage to the internal light enhancement tube, so the 1PN34 with the objective lens cover can also be used during the day. At night, it is usually necessary to remove the lens cover and use it directly.

scope is in perfect condition, and only infrared rays can enter after installation. If the other party uses active infrared night vision equipment, or has an engine that emits heat, the probability of being discovered by this passive infrared night vision device will increase.

1 PN34 battery compartment is open. It originally used special batteries, but it was converted to use two AA batteries (No. 5) for power supply.

the reticle is lit, because it is tested in a black room, only the luminous reticle can be seen.

this is a photo taken by staff testing the 1PN34 night vision scope in Tokyo, about 100 meters away. Considering the bright lights at night in Tokyo, the staff did not remove the lens cover and found a relatively dark building. The outline of the building and the shape of the window can be clearly seen, and the optical distortion of the image can be seen at the same time.

staff used a 1PN34 night vision sight to observe another building, which was almost the same distance from the previous one. The infrared filter cover was added during this observation, and the quality of the image and reticle looks better. The edge of the field of view is still distorted. It seems that the early vacuum tube technology will produce such a problem. The distortion problem is solved in the second generation night vision device.

this is the 1PN34 night vision scope ranging method issued by the Soviet Union. The reference objects are tanks and people, and the heights are 2.7 meters and 1.5 meters respectively. The distance of the target is estimated by the size of the image in the field of view of the night vision device. This method is difficult to remember and can only be judged by experience.

in the 1970 s, 1PN34 began to be equipped. In the recent conflict in eastern Ukraine, this kind of scope can also be seen.

NSPU night vision scope also appeared on the Cuban military parade. It was installed on a mysterious sniper rifle. It looks like a bolt-on rifle, with a caliber of 7.62 × 54mmR, and is called the Alejandro precision rifle. However, because the NSPU night vision scope also has 1PN58, the two are similar in appearance, and it is difficult to determine which model it is.

Antique Gun Store displayed the 1PN34 night vision scope, a Japanese gun fan said that he had the same night vision scope and uploaded photos. You can see that this sight is in very good condition, as well as the original metal collection box, the number of the collection box is exactly the same as the number on the frame.

the effect of night observation, you can see that the font on the sign is very clear, but the gun fan did not disclose whether the objective cover or infrared filter cover was used. He said that the reticle of this night vision scope cannot be lit, so the reticle cannot be seen in the field of view.

At the same time, he also uploaded photos taken by his mobile phone, which can be compared with photos of night vision devices.

, I felt two things: Japanese antique shops are really magical, and there are many masters of Japanese dead houses.
