The submachine gun "Heather" differs from the so-called peers in firing range. Weapons can hit a target at a distance of up to 200 meters. In addition to its high range, the submachine gun also has other powerful parameters. For example, it easily breaks through individual enemy armor protection.
The first weapons developments were carried out at the end of the last century, and the modernized model, which is used by special services, was presented only in 1999.
The compact submachine gun is perfect for close combat and defense. PP is convenient in shooting with a butt, with hands, offhand. During the battle provides a high density of fire in a short period of time.
The pistol cartridge, which has a small amount of gas and a small initial speed, facilitates the use of silencers.
Features of a specially designed pistol
Experiments on new weapons began in 1993. Since that time, the development of a new development work has also begun under a special code. The submachine gun SR-2 "Heather" is adapted for the 9x21 cartridge. SR stands for "special development." The final version of the "Heather" was adopted in 2000.
The main features of the SR-2 software are:
- A rare automation system and a node for locking the bore.
- The removal of powder gases into the gas chamber, which is located above the barrel.
- The shutter frame is rigidly connected to the rod of the gas piston.
- The return spring is located in the channel of the shutter frame.
- The shutter is equipped with six combat ledges.
The reload handle is located on the right side. Due to this, the overall size of the weapon is significantly reduced. The compensator is attached to the muzzle. The automation box is cold stamped from a sheet of steel.
The design and operation of the submachine gun
The shock mechanism of the Russian submachine gun "Veresk" - shock type. The fuse box is located on the right. When turned on in the extreme position, the fuse blocks the descent, and the flag overlaps the groove for the recharge handle to go through. Another flag translator is located on the left. It sets a single or next fire. Toggle the checkbox with your thumb.
The supply of cartridges comes from a direct box magazine. A feature of the store is the chess arrangement of cartridges. After the ammunition is consumed, the store is discarded after pressing its latch. The shooting process is equally convenient for both hands.
A fly with a fuse is installed near the muzzle of the barrel. The whole is designed for shooting at a distance of 200 meters. The automation cover is adapted for the installation of an optical or collimator sight.
The stock is made by metal stamping. It folds up and down.
Submachine gun SR-2M "Heather" - a modernized version of the above weapons. The fuse flag has been changed in it. In the SR-2M, the muzzle device was replaced, and a folding front handle appeared on the fore-end.
The performance characteristics of the software SR-2M
- The mass of weapons without equipment: 1650
- Length of software with folded butt: 603 mm.
- With folded: 350 mm.
- Barrel length: 174 mm.
- Number of rifling: 6.
- Sight range: up to 200 m.
- Magazine capacity: 20/30 rounds.
It is worth noting that a collimator sight (approximately 300 grams) and an equipped magazine are added to the weight.
The submachine gun is adapted for the cartridge SP10, SP11 and 7BTZ. The initial velocity of the bullet depends on the type of cartridge and is: in the first case - 440 m / s, in the second - 415 m / s, and in the third - 430 m / s. Cartridge SP11 is equipped with a low-ricochet bullet, and 7BTZ has armor-piercing tracer.
The characteristics of the Veresk submachine gun allow firing at a distance of 100-200 meters. A front sight with a fuse are located on the extreme front of the barrel. A collimator sight with a 6-o field of view is attached to the box lid. Such sights are the main when conducting a battle at short range.
Design features of the submachine gun
The stock of weapons is made by cold stamping of steel. The control handle and fore-end are made of impact-resistant plastic. The handle is made integral with the trigger guard. Ahead emphasis is established in front of it. Handguard covers the trunk.
For the convenience of firing from a position with outstretched arms, a front bend is designed on the trigger guard (as for shooting with a two-handed grip).
In the upgraded version, the hard stop on the forend is replaced by a folding front handle. This feature increases the controllability of weapons and accuracy of fire. The fuse box has also been upgraded. In the new version, the muzzle device is presented in the form of a muzzle-stop. This feature allows you to protect the shooter's brush from burns with powder gases and displacement forward.
The Veresk submachine gun is worn on a belt and discreetly, using a suspension that holds both weapons and a spare magazine.
Weapon automation
In the SR-2 “Veresk” software, gas exhaust automation is used with the barrel locked at the time of the shot.
The gas piston in the cylinder is located above the barrel. When fired by a piston, a bolt carrier is actuated (in which a bolt with 6 combat stops is located). The cocking handle is rigidly fixed to the right of the bolt frame.
It is possible to conduct automatic and single fire. The right fuse lever has 2 modes: O - fire, P - fuse. The left one serves as a translator of fire modes: one point corresponds to a single shot, three points to automatic fire.
Cartridges are supplied from box magazines. The design of the Veresk submachine gun is equipped with open standard sights.
PP design for incomplete disassembly
The device consists of:
- From the return mechanism.
- Shutter frame.
- Combustion spring with a guide.
- Drummer.
- Shutter.
- Forearm.
- Barrel with automation.
- Trigger mechanism.
- Stock.
- Other surface details.
- The store.
Standard equipment consists of the following elements:
- Suspension (bag for spare clip + shoulder suspension + holster). It is used for stealth carrying.
- Belt. Designed for open carrying. Adjustable in length.
- Ramrod (used when cleaning weapon elements).
- Bags.
- Case.
- Other accessories for cleaning and disassembling.
The Veresk submachine gun needs regular cleaning after each use. Timely care significantly increases the resource reserve and service life. It is advisable to clean immediately after firing.
Advanced software series SR-2
The new automation system and an unusual stock are selected in accordance with the powerful ammunition, for which the weapons are designed. PP automation mechanisms are reliable in adverse conditions (for example, with increased dust, humidity). The range of operating temperatures is from -50 to +50 degrees. A silencer can also be installed on the PCB.
When developing a guidance system, it was planned to use only mechanical and flip diopter sights. A little later, the collimator sight, which is the main one, was added to the layout of the Veresk SP-2MP submachine gun. The mechanical one was slightly modified - there was only one pillar left in it. The distance to the target is taken into account by taking out the aiming point in height. A similar method is convenient for experienced shooters.
Ammunition for "Heather"
The submachine gun is used in special operations forces. In view of this, the weapon is adapted for various types of supplies of caliber 9 × 21 mm:
- SP10 - with a steel bullet of increased armor penetration. This type of ammunition affects the manpower of the enemy at a distance of up to 200 meters, and is also capable of harming individual means of armor protection.
- SP11 - ammunition created using a lead core.
- SP12 - cartridge with an expansive bullet. It provides enhanced stopping power.
- SP13 - supplies with a tracer bullet.
According to experts, the damaging effect of the cartridges of the Veresk submachine gun is up to three times higher than that of supplies of PM 9 × 18 mm, and 2 times higher than that of 9 × 19 mm.
