CheyTac M-200 (English: CheyTac Intervention M-200; Intervention, meaning: intervention) is a manual bolt-operated sniper rifle produced by the American CheyTac company. Its main purpose is to intercept long-distance soft targets. It uses 7 rounds
Capacity detachable single-column magazine feeds ammunition, firing .408 CheyTac or .375 CheyTac bullets. According to CheyTac documents, the entire system is capable of shooting with an accuracy of less than 1 arc minute at a distance of up to 2,286 meters (2,500 yards), which is
The one with the longest range among all modern sniper rifles. It should be noted that "intervention" is the name given to this series of weapons by Cheyenne Tactical Company. It does not represent its purpose and should be translated as "intervention" rather than "tactical interference."
design
The design of the CheyTac M-200 is based on the EDM Windrunner M96 sniper rifle (English: EDM Arms Windrunner M96). It uses a manual bolt operation and is equipped with a freely retractable stock. The stock is equipped with a folding rear leg and a cheek rest.
The barrel is of a floating design and is only assembled with the receiver, and is protected by a cylindrical handguard. The barrel and bolt also have grooves to reduce weight and increase tension, and both can be quickly replaced or disassembled.
It is convenient for transportation. The large handle in front of the magazine is used to carry the gun easily and can be folded down when not in use. The bipod and gun stock attached in front of the handguard are equipped with a folding rear tripod for raising on the ground.
It is stable and can be folded when not in use. The PGRS-1 brake on the muzzle can be equipped with a silencer. There are finger grooves on the pistol grip, which makes shooting more stable and accurate. Since this gun does not have any mechanical sights
For equipment (rear sight and front sight), the scope and/or night vision goggles must be installed on the tactical rail on the top of the receiver, while other tactical accessories can be installed on the tactical rail on the front.
long range rifle system
The CheyTac M-200 is part of CheyTac's "Long Range Rifle System" (English: Long Range Rifle System, referred to as: LRRS), which includes the CheyTac tactical bullet ballistics computer (a commercial personal digital assistant equipped with CheyTac's ballistics software), connected to the personal digital assistant
Assistant's Kestrel 4000 compact weather tracking device (wind, temperature, humidity and pressure sensors) and Vector IV laser rangefinder, Nightforce NXS5.5-
22x56 scope and muzzle device (muzzle brake and silencer).
Cartridges, bullets and barrels
CheyTac Co., Ltd. is constantly trying to develop the best shell, bullet and barrel configuration in order to be able to snipe at long distances. It is for this reason that CheyTac and the now (2010) defunct Lost River Ballistic Technologies (English: Lost River Ballistic Technologies)
) developed the .408 CheyTac, an extremely low-traction, single-metal bullet developed specifically for use in long-range rifle systems. Lost River Ballistic Technologies (statement issued by Mr. Warren Jensen) said, ".
408CheyTac is the first bullet/rifle system that uses parallel, stable flight. In order to achieve a balanced linear resistance during bullet flight, it must be balanced with the resistance during rotation to maintain a very good streamlined pointed projectile.
The top end (bullet tip), and reduce the air resistance encountered when the bullet flies out of the muzzle. It must achieve very little error, will not deviate seriously in the most extreme range, and can return to the transonic range
The result is that it will still fly extremely accurately in the future. This is very difficult to achieve with ammunition for small arms. Even if you try to make a non-single metal projectile achieve balanced flight, this is a huge problem mathematically.
And unfavorable conditions. Because the rotational mass/surface area ratio is too high." The patent for the balanced flight of the warhead can be found in the U.S. Patent Office's Ammunition with Controlled Rotation (U.S. Patent No. 6629669). According to the meaning of the patent invention diagram, the warhead
Notches on the missile and the launch should slow down from transonic to subsonic speeds during supersonic flight, allowing the projectile to travel in a stable and predictable manner to an effective range of over 2,743.2 meters (3,000 yards). This means, among other things
In addition to several prerequisites, the barrel must have a specific rifling twist size to meet the axial value of air resistance on the bullet surface, thereby reducing the bullet rotation rate and achieving balanced flight. In order to achieve balanced flight, the .408 CheyTac bullet
The rifling twist is set at 1:13 inches (330.2 mm), the bore diameter is 8.4080 inches (10.36 mm), the bore diameter is .4010 inches (10.19 mm), and the thread top diameter is 0.050 inches (1.27 mm).
), square cut, no taper. The rifling twist of the .375 CheyTac bullet later developed from the .408 CheyTac bullet was set at 1:11.5 inches (292.1 mm).
Muzzle brake and silencer
An important factor that can reduce the recoil of .408 CheyTac is the PGRS-1 muzzle brake developed by MacArthur. Its design was invented by firearms technician and firearms inventor Bruce McArthur (English: Bruce McArthur), who was located in Michigan.
Chairman of the state's Flint & Frizzen Gun Shop (English: Flint & Frizzen Gun Shop). The MacArthur design uses high-pressure gas attached to the bullet to brake before leaving the muzzle brake. The silencer installed on the CheyTac muzzle brake is made of
The silencer produced by OPSINC is made of stainless steel. The integrated all-stainless steel silencer does not have any replaceable parts inside to ensure that the life of the silencer is equal to or even exceeds the life of the rifle. When the silencer is completely filled with water, the silencer will
Drain all the water within 6 seconds after the water comes out and continue to use it. If the user needs to adjust the muzzle brake, he must re-zero the aiming height of the scope by 6 arc minutes.
Optical sight systems for day and night
The CheyTacM-200 has two different optical scopes that can be used during the day. The primary scope is the NXS5.5-22x56 variable magnification scope with an objective lens length of 56 mm (2.2 inches). As a backup second
The first sight is the SN-9 optical sight made in the United States. The night vision goggle system of choice is the AN/PVS-14 third-generation peaked single-eye night vision goggle. The AN/PVS-14 needs to be connected to the
Optical sights are used during the day. The AN/PEQ-2 Laser/Infrared Designator (LAM) system is used as a support for the night vision goggle system, especially when there is not enough ambient light or when infrared laser is required for further use.
It is used under the conditions of target lighting and aiming. The device needs to be connected to the top of the sight using a bracket made of titanium.
Portable weather and environment sensor components
The Kestrel 4000 (English: Kestrel 4000) weather and environmental sensor is used to measure wind speed, air temperature and air pressure. It also collects relative humidity, wind chill and dew point. All these data are fed directly to the tactical bullet trajectory calculation computer, and
Normally there is no need to enter data manually.
laser rangefinder
Navigation IV military laser rangefinder telescope. Navigation IV (English: VectorIV) military laser rangefinder is used to establish ranging data. High-end laser rangefinders can very accurately measure targets at distances exceeding 2,000 meters (2,187.23 yards), for
It is the most expensive piece of equipment for civilian long-range shooters.
Advanced bullet trajectory calculation computer
CheyTac's Advanced Ballistic Computer (ABC) system software suite is a long-range sniper personal digital assistant installed on snipers. It was developed to improve prediction capabilities. Its prediction capabilities are based on
Actual bullet flight data, and the data comes from the high-speed Weibel 1000e Doppler radar that is still in the testing stage at the U.S. military range in Yuma, Arizona. The calculation method established by engineers is to use known mathematical formulas to calculate each
The pattern of seed bullet trajectory, especially the data obtained from special tests, is calculated according to the table to ensure that the data is consistent.
The system provides a simple set of altitude and deviation calculations, and uses complete external environmental factors, user and firearm system specifications integrated data to arrive at a solution, so that the operation of small arms can be achieved within the maximum effective range.
Achieve high-precision long-range ballistic attacks on any specific number of targets.
The software suite can run on a variety of personal digital assistants, such as rugged and military-spec R-PDAs using the Windows Mobile 2003 operating system, and will utilize handheld weather and environment sensor components and navigation from the Kestrel 4000
IV (English: VectorIV) laser rangefinder binoculars directly input data for calculation.
When the calculation method of bullet trajectory data established by engineers using Doppler radar is not available at the time of shooting, the Advanced Bullet Ballistics Computer, like all other ballistic prediction computer programs, can only rely on calculating various bullet trajectory patterns.
Reduced the software suite's ability to predict long-range fire.
data sheet
The reason for providing the attached printed data sheet is to use it when the tactical ballistic calculation computer fails or the battery supplying power to the device is exhausted. The effectiveness of long-range shooting of a sniper without computer support will be greatly weakened.
Because they may rely heavily on computer support to obtain the correct ballistic solution.
Function
record
In Arco, Idaho, the CheyTac M-200 set the world record for the best long-range shooting group, with three rounds hitting a group of 42.2 centimeters (16.69 inches) at about 2,122.32 meters (2,321 yards). On TV
In the show Future Weapons Season 2 Episode 13 (air sequence is Episode 19) "MassiveAttack" (English: MassiveAttack), Richard, a former Navy SEAL and host of the show,
Richard Machowicz, in Arco, Idaho, tested nine shots, the first three of which hit a metal man-shaped gun target at a distance of 822.96 meters (900 yards), and then the
Three of the six shots fired in the "real test" hit the metal man-shaped gun target at a distance of 2,313.43 meters (2,530 yards).
Accuracy
CheyTac claims in a November 13, 2006 information document that "the CheyTac Long Range Rifle System is positioned as an anti-personnel system for use at a range of 1,828.8 meters (2,000 yards). The primary design purpose of the 408 caliber is as a
An anti-personnel system with the largest range. According to data obtained so far, the group at 914.4 meters (1,000 yards) is 17.78-22.86 centimeters (7-9 inches), and the group at 1,371.6 meters (1,500 yards) is 25.4
centimeters (10 inches) and 38.1 centimeters (15 inches) at 1,828.8 meters (2,000 yards)
The gun also achieved records of 48.26 cm (19 inches) at 1,920.24 meters (2,100 yards) and 73.66 cm (29 inches) at 2,194.56 meters (2,400 yards). The gun also achieved records at 2,743.2 meters (3,000 yards).
The vertical dispersion group is still less than 1 arc minute.
Derivative
The CheyTac M200 sniper rifle can be divided into the following variants: M-200 standard: barrel length 736.6 mm (29 inches), telescopic stock and detachable magazine supply.
M-200 carbine type: barrel length 660.4 mm (26 inches), telescopic stock and detachable magazine for ammunition.
M-310: Single-shot and repeating-shot variants have a barrel length of 736.6 mm (29 inches) and a fixed stock.
M-325: Single-shot, repeating-shot and tactical variants have a barrel length of 711.2 mm (28 inches) and a fixed stock.
The main performance difference between different derivatives is that the muzzle velocity is determined by the length of the barrel. The higher the muzzle velocity, the effective range of the rifle will be increased. Everything else is the same. In addition, the M-200 standard type and M-
200 carbine models all have a detachable magazine feed and telescopic butt design, while other derivatives use a fiberglass-reinforced plastic fixed McMillan butt design.
