Sniper rifle ORSIS SE T-5000 .338 Grafit Black
A new T-5000 ORSIS sniper rifle has been developed in Russia, which will be able to replace the currently popular samples of foreign production in domestic special forces.
Needless to say, snipers in current armed conflicts and special and counter-terrorist operations are of considerable importance. In this regard, in modern conditions, the requirements for sniper arms in the field of its characteristics such as range of aimed shooting, accuracy, penetration and destructive action of a bullet, the possibility of using in different conditions day and night, maneuverability. It is also well known that in the domestic armament system the “niche” of a high-precision sniper rifle is still poorly filled (this is not only the rifle itself, but also the “cartridge-weapon-sight” complex, each element of which makes a significant contribution to the weapon’s characteristics) . The SVN 7,62-mm rifle is an excellent military weapon — it is no longer very suitable for solving a number of sniper tasks for its accuracy and accuracy, especially at ranges over 800 m. This required the addition of a SVD with a rifle with significantly improved accuracy and a multiple scope. Snipers of the special forces units of the Russian security agencies are now actively using foreign sniper rifles (British AW "Ecuresi International", Finnish TRG-21 and TRG-22 "Sako", German AMP, etc.). It is therefore not surprising that any new domestic-made sniper rifle attracts the most lively interest in itself - no matter what class a professional is, he needs a specialized professional tool for success.
In May 2011, the release of their own sniper rifles Under the brand T-5000 ORSIS (Latinized abbreviation "weapon systems"), the Promtechnology Group of Companies began in Moscow. The general public rifles were presented in September 2011, the exhibition of weapons in Nizhny Tagil. Rifles are called "tactical." Apparently, this is not only a tribute to the “foreign” fashion (the name “tactical rifle” really became quite common abroad), but also an indication that the sample can be effectively used in a variety of tactical situations. T-5000 was originally presented in two calibers, widely distributed in specialized sniper weapons - chambered for .308 "hard drive" (.308 Win, 7,62x51) and .338 "paw magnum" (.338 Lapua Magnum, 8,58X69). Soon, an option was added for the .300 “HDD Magnum” (.300 Win Magnum, 7,62X67).
To test the combat qualities of the rifle, it was handed over to special forces of the Russian law enforcement agencies - the FSB, the Federal Guard Service, and others - and further refinement of the weapon was carried out taking into account the comments of professional users. The ideologist and chief designer of the rifle was A. M. Sorokin, general director of Promtechnology Group of Companies, who worked on the rifle scheme and made the main sketches of the sample. It is worth noting that D.Yu. Semizorov, a veteran of the Vympel special purpose unit (since November 5000, general director of the Federal State Unitary Enterprise TsNIITOCHMASH), made a considerable contribution to the creation and development of the T-2012, by the way, at the exhibition “Engineering Technologies “In June 2012, the improved ORSIS T-5000 rifles chambered for .308“ Winchester ”and .338“ Paw Magnum ”were exhibited at the“ Tsiniitochmash ”stand. The very effective advertising of the new weapon in June of the same year 2012 of the Office of the A team of the FSB Special Purpose Center at the World Sniper Shooting Championship held in Hungary - “Alfovtsy” performed on them with T-5000. About this, however, domestic media have written quite a lot.
Now about the rifles themselves.

Like many high-precision sniper rifles, the T-5000 was created on the basis of a sports model. Characteristic choice for high-precision sniper rifle magazine layout and well-established foreign rounds. The latter can again be explained not only by the calculation on the “commercial” market (and the Promtekhnologii Group of Companies is a rare example of thoroughly supplied “private” weapons production for the domestic industry), but also by the deplorable situation with domestic sniper ammunition.
The barrel of the T-5000 rifle, made of special stainless steel, is mounted in the receiver console, a slit muzzle brake compensator is mounted on the muzzle of the barrel, absorbing up to 50% recoil energy. Depending on the caliber of the cartridge, four or six right-side rifling of a rectangular shape are made in the barrel bore. Longitudinal valleys on the outer surface of the trunk allow for the required stiffness while facilitating.
The combat larva of the longitudinally sliding rotary shutter is made according to the “compromise” scheme between the closures of the Remington schemes. The 700 and Mauser models - with two lugs, a cup under the cap of the cartridge case, an ejector and a spring-loaded reflector directly ejecting the cartridge into the window. boxes after removal from the chamber. This scheme allows for reloading with the least noise, the absence in the battle of the larva cut for the passage of the reflector makes locking the barrel more secure and safer. Locking bolt stops when locking are included in the grooves of the receiver. When the shutter is closed, the cap of the liner is covered by concentric rings - a cup of the bolt and the receiver. The shutter is made relatively large, which allows it to provide strength and strengthen the locking assembly. In the stem of the bolt there are holes for the discharge of powder gases in case of their breakthrough through the chamber or the sleeve. Respectively patron “short” or “long” bolt group is used. Receiver and bolt are made of stainless steel.
The trigger mechanism is made with the placement of the striker and the helical combat spring in the cavity of the bolt.
The tail of the drummer, which protrudes behind the slide, allows the state of the percussion mechanism to be determined visually or by touch. The cocking of the firing pin is performed by unlocking (opening) the bolt. Descent - with a warning, the descent force can be adjusted within 0,5-0,9 kgf. Quite a smooth descent contributes to shooting accuracy. A three-position fuse with a flag rotating in a horizontal plane is mounted in the rear part of the gate: in the “safety” position (rear position of the flag), the drummer and the bolt are locked, in the disassembly position (middle), the drummer is blocked, the bolt is free, can be easily pulled back during disassembly (to do this, press the shutter latch on the left side of the receiver), the front position of the flag corresponds to the “fire” state (a bright orange dot opens). When the shutter is closed, its large handle is above the trigger guard, and the fuse box head is accessible to the thumb of the shooter.
Meals from the direct detachable metal shop. Strong fastening of the store contributes to the neck of the receiver, which is part of the lodge.
The layout and balance of the rifle provide a reduction in the “tilting” recoil action. The composite bed is made of lightweight aluminum alloy D16T, for ease of transport and disassembly T-5000 is equipped with a butt folding to the left. The hinged butt assembly is made of steel for greater strength, reliability and elimination of backlash, the joints are made “steel-to-steel”. The butt is equipped with a butt pad, made of wear-resistant rubber and height-adjustable, and height-adjustable stop under the cheek arrow. The butt length is determined by the spacer under the butt pad and is not otherwise adjustable. The receiver rests on the box through a kind of layer impregnated with epoxy resin, which provides not only a better fit, but also a more even distribution of loads.
During the completion of the bed received a number of changes and additions. The most conspicuous is the appearance of the plastic lining of the forearm. Prior to that, the box was calculated primarily on shooting from the stop with the left hand holding the butt (for the right-handed arrow) - which, in fact, was the shape of the butt. According to the comments of the users, the rifle had to be adapted for shooting from a standing position, sitting, from the knee, so that a plastic overlay of the forearm was required. Subsequently, the pad was still lengthened. The shape of the plastic pistol grip control has been improved, in particular, it has received an upper bend in the rear. Thus, the hands of the shooter practically do not touch metal parts, which is especially convenient in cold or, on the contrary, very hot weather. The stock in the folded position was initially fixed by a magnetic latch, but practical tests of the rifle showed the unreliability of such a solution, and a mechanical latch was inserted into the design. The screw, which regulates the position of the “cheek” of the butt, is now rotated “in steps,” the shooter can change its position “on clicks” and it is easy to remember the once found comfortable position. That is, the ergonomics of the weapon improved, first of all. A Picattini-type slider mounted on the receiver allows you to mount various types of sights. The manufacturer itself recommends the use of rifles with pancratic optical sights — by American “Night Force” or domestic comparatively new, but well-proven “Daedalus”. In addition, the Picattini bar can be attached to the front of the box for mounting a pre-objective night attachment to the sight.
In front of the forearm there is a mount for a bipod and rifle belt. Standard rifle completed with a folding height-adjustable bipod of the type "Harris Bipod" - another element widely used in sniper weapons in different countries.
The design of the rifle has implemented a number of generally well-known and proven solutions, but they have been carefully selected, developed and applied in the complex.

Current requirements for a high-precision sniper rifle imply a deviation of hits of no more than one angular minute in the absence of wind exposure. Accuracy of shooting T-5000 is characterized by the following data - dispersion hits falls within 0,5 angular minute (MOA) when using high-quality ammunition. Here the manufacturer is also quite strict, recommending rifle cartridges of such proven manufacturers as the German RWS and the Finnish Lapua.
It is clear what a significant contribution to the ballistic qualities of weapons makes the technology of its production. The ORSIS weapon is produced at the Moscow plant of Promtechnologii Group of Companies, which widely uses modern machine tools with numerical program control. For the manufacture of rifling sniper rifles at the factory used single-pass cutting, more precisely, planing with a tapestry. This technology is not as productive as dornirovanie, and quite expensive, however, provides a higher quality bore. It is no coincidence that it is still widely used for the manufacture of high-precision rifle barrels. In one pass through the bore of the barrel, trellis processes one rifle, and removes metal to a depth of about 1 microns, so that at least one 80 passage is required to make one rifling. The CNC machine allows for a fairly wide range to change the number, shape and angle of the rifling. The machine for making grooves is the pride of Promtechnology specialists. To demonstrate the absence of vibrations and smoothness of work, the old method is used here - a coin is placed on the edge of the working machine. The tolerance on the depth of the rifling is 2-2,5 micron (0,002-0,0025 mm), when deploying the chamber, around 2 micron. Instrumental control of the barrel in the laboratory - by length, caliber, cleanliness of processing, pitch of grooves, the ratio of the width of fields and grooves, etc. - is carried out using optical and digital equipment with digital video recording equipment. In the manufacture of the receiver and the gate is used EDM processing. It should be noted that initially a version of the shutter with screw grooves (grooves) milled on the stem, designed to retain fine particles or moisture, was introduced, but with further refinement of such grooves refused.
The “cheek” and pistol grip are milled from high-strength plastic.
On the whole, production is not at all a “transfer to the Russian soil” of the finished technology of any foreign enterprise, but was created anew with the selection of appropriate equipment - mainly foreign-made.
The outer metal surfaces of the rifle have a non-glare ceramic coating of the ceracot type (Cerakote, a solution developed by the American company NIC-Industries), which provides, in particular, high wear resistance of parts. The colors used are known as “black graphite”, “gray sniper”, sandy yellow, olive.
In general, the “cartridge-weapon-sight” complex turns out to be quite expensive, but, on the other hand, the sniper rifle is a professional tool, its certain rise is inevitable, which can be seen in the example of both foreign and domestic sniper complexes.
The rifle T-5000 is offered in various trim levels, in particular, it can be supplied with various belt options. The “Debt-MZ” tactical weapon belt, which can be mounted on the T-5000 in two-point, three-point (“tactical”, with the weapon moving the shooter along the belt in different positions) and biathlon scheme (behind the back like a backpack), looks very original .
