Carbine KO-30 S: reviews, price, technical characteristics, review

Review of the KO-30 S carbine

Model 1891/1930 was a dragoon carbine with a slightly different sight and a simplified chamber. The weapon was used as a combat weapon in cavalry units. After World War II, the weapon became completely obsolete and was mothballed.

However, the resulting shortage of good hunting carbines led to the Mosin rifles being removed from the warehouse and converted into hunting rifles. Moreover, in many cases the carbines were re-barreled to a different caliber. Model KO-30 S is authentic.

Rifles of the 1891/1930 model are of collector's value today.

A review of the KO-30 S rifle is given in that video:

Advantages and disadvantages

The carbines produced on the basis of the Mosin rifle were somewhat different. In the combat version, the bolt handle remained straight and short. In the sniper model, the handle is longer and bent down. This is of fundamental importance: military weapons, especially those released later, by 1944, participated in infantry attacks, that is, they played the role of a bayonet weapon. And such use has an extremely negative effect on the quality of shooting.

The sniper version excludes such use. Accordingly, the model made on the basis of a sniper rifle has much higher ballistic characteristics.

The advantages of the weapon are the following:

An optical sight is installed on the sniper rifle. There is no such option on a conventional combat carbine;
on models starting from 1930, cylindrical boxes are installed - in the left side you can see 2 cylindrical holes or traces of their welding. This is also a sign of a sniper, that is, a rifle with good accuracy;
A remarkable feature of Mosin rifles is the quality of the barrel. This is indicated by a clean barrel finish and old bluing. On new models, the barrel and chamber are chrome-plated;
The weapon is designed for hunting large animals - wild boar, elk. A shell bullet can easily pierce through the trunk of a brother-in-law with a girth of thickness from a distance of 100 m;
the bullet's flight range is 3 km;
The carbine can be used in any weather conditions at temperatures from -50 to +50 C.

The disadvantages of the product are as follows:

the magazine has to be filled with cartridges “one at a time” in order to prevent the sleeve edge of the upper cartridge from jumping over the edge of the lower one;
the screws holding the stock to the barrel tend to come loose. The tightening of the screws must be monitored, as this affects the accuracy of shooting;
The quality of a weapon is highly dependent on previous use. Rifles produced after 1942 are characterized by poor barrel quality and, in principle, are not designed for use as a sniper.

Purpose

Model KO-30 S is a medium caliber carbine.

It is also used for hunting birds - black grouse and wood grouse.

Varieties

By rifle KO-30 S, as well as KO 91/30, they mean a combat carbine of the 1891/1930 model converted into a hunting weapon. The difference between the individual modifications is so small that in most cases it is not considered as a separate variety.

The most famous version is the KO-30 S with an optical sight. Moreover, its placement is such that you can use the open front sight without removing the OP.
A modification is available, equipped only with an open mechanical sight.
KO 91/30 M – is equipped with a new forged barrel with chrome plating of both the barrel itself and the chamber. Moreover, 2 models are produced with different barrel lengths: 550 mm with a total length of 1055 mm, and 610 mm with a length of 1115 mm.

KO-30-S S PU – medium-caliber carbine for amateur and professional hunting

The carbine is intended for professional and amateur hunting at ambient temperatures from + 50 °C to -50 °C, for novice athletes, for participants in reconstructions and collectors. The carbine is suitable even for recreational shooting at non-standard targets. But we must remember that this is a serious weapon, designed for hunting large animals - wild boar, elk. A shell bullet can easily pierce a tree trunk with a girth of thickness from a distance of 100 m.

Operating principle

The mechanism of operation of the carbine does not differ from the standard operation scheme of a three-line rifle.

The shutter is opened by turning the handle to the left. In this case, the trigger is pulled back, and the mainspring is partially compressed - pre-compression. The firing pin goes into the channel of the combat cylinder, the protrusions move upward due to the supporting planes and the barrel channel is unlocked.
The bolt is pulled back all the way - at the same time the cartridge from the magazine goes to the chambering line.
The bolt moves forward - the cartridge is in the chamber.
The handle is turned to the right and the bolt is closed. In this case, the combat protrusions extend beyond the ledges of the box and the barrel is locked. The mainspring is pressed harder - final compression.
They press the trigger - the sear disengages from the hammer, the hammer is released, the spring straightens and the hammer striker forcefully breaks the cartridge primer - this is how the shot occurs.
The bolt is pulled back - at the same time, the ejector pulls the cartridge case out of the chamber, and the cut-off reflector throws it out of the receiver.

When storing, carrying and transporting, the carabiner must be set to the “safety” position. In this mode, the combat platoon is placed in the recess of the box. The safety ridge of the trigger rests against the box, which prevents an accidental shot. In fact, in this position you cannot even open the shutter.

A mandatory requirement is to store the rifle unloaded and set to the “safety” position. Ammunition and rifle must be stored separately.

Disassembly

The weapon is disassembled and reassembled for cleaning and lubrication after firing. In this case, you cannot apply significant force, otherwise the parts may become deformed.

Partial disassembly - for lubrication, includes the following steps:

unscrew and remove the cleaning rod. Remove the cover of the magazine box;
holding the combat cylinder and the handle, retract the trigger until a protrusion comes out of the socket on the screw cut. Then turn the trigger to the left and release;
holding the bolt, move the bar with the combat cylinder forward and disconnect it from the bolt stem;
the combat larva is separated from the bar;
the firing pin is put into the gasket, the handle is pressed and the mainspring is compressed. In this position, unscrew the trigger from the firing pin and remove the firing pin with the spring;
the mainspring is removed from the firing pin.

If the weapon is to be stored for a long time or the carbine is exposed to moisture, the weapon is completely disassembled. In addition to the above steps, the following are added:

the stop and tail screws are unscrewed 2 turns and the stock rings are moved forward;
set the carbine in a vertical position, completely unscrew the screws, disconnect the magazine box, and then the barrel from the stock;
