CheyTac Intervention
From Wikipedia, the free encyclopedia
The CheyTac Intervention is an American-made sniper rifle designed by CheyTac LLC. for long range soft target interdiction (ie, anti-personnel sniper). The CheyTac Intervention comes in five varieties: the CheyTac Intervention M-200, the M-200 Carbine, the M-200 CIV, the M-310 SS, and the M-310 R. Both the M-200 and the M-200 Carbine are restricted for Military and law enforcement use only. The M-200 CIV, the M-310 ss, and the M-310 R are available to civilians.
The CheyTac M-200 holds the world record for best group at a distance, landing 3 bullets within 16-5/8 inches (42 cm) at 2,321 yards (2,122 m).

[edit] Ballistics
The CheyTac Intervention M200 rifle is fed using a detachable single stack magazine, which holds 7 rounds. It fires .408 CheyTac ammunition. CheyTac papers state that the entire system is capable of delivering sub-MOA accuracy at the ranges of up to 2500 yards (2270 meters), one of the longest ranges of all modern-day sniper rifles.
[edit] Technical data
- Caliber: .408 Chey Tac
- Length: 1400 mm (stock retracted), 1220 mm (stock collapsed)
- Barrel: 762 mm (30 in)
- Magazine: 7 rounds
- Operation: bolt-action
- Range: 2500 yd (2270 m)
[edit] Support equipment
The CheyTac Intervention M200 rifle is part of CheyTac's 'Long Range Rifle System' (LRRS), which includes CheyTac tactical ballistic computer (commercial PDA with CheyTac ballistic software), Nightforce NXS 5.5-22X scope, Kestrel 4000 wind/temperature/atmospheric pressure sensors, linked to the PDA and OPS INC muzzle brake and suppressor.
[edit] OPS INC Muzzle Brake and Suppressor
The CheyTac OPS INC suppressor, manufactured by OPS INC, is a stainless steel long life suppressor. The suppressor attaches in a unique manner to enhance system accuracy and adds 25 to 30 ft/s (8 to 9 m/s) to the standard muzzle velocity. The all stainless steel construction with no replaceable parts guarantees a suppressor life that equals or exceeds the life of the rifle. Even when totally filled with water, the suppressor can be drained in 6 seconds that allows very rapid employment when emerging from water. If the operator chooses to switch to the muzzle brake, a repeatable 6 MOA zero change for elevation is required.
[edit] Day and Night Optical Sight Systems
There are two different day optical sights available. The primary sight is the Nightforce NXS 5.5 - 22X variable magnification telescopic sight with a 56 mm Objective. The alternate sight that is still in development is the US Optics SN-9. The night vision system chosen is the AN/PVS-14 GEN III Pinnacle monocular. The PVS-14 is attached to the day optic using the Monoloc device. The Monoloc is already in use by several SOCOM units as well as the PVS-14. An AN/PEQ-2 IR Laser is used for system support with the night vision sight under conditions where there is insufficient ambient light or the IR Laser is needed for further target illumination. The device is attached to a titanium strut.
[edit] KESTREL 4000 meteorological and environmental sensor package
The KESTREL 4000 meteorological and environmental sensor package is used to measure the wind, air temperature, and air pressure. It also collects relative humidity, wind chill, and dew point. All of these points of data will be fed directly into the tactical computer so that no manual input is necessary.
[edit] Advanced Ballistic Computer (ABC) System software package
The CheyTac, LLC Advanced Ballistic Computer (ABC) System software package was developed to enhance the long range predictive capabilities of a sniper’s handheld computer. Its predictive capabilities are based on actual bullet flight data derived from test sessions on the high speed Weibel Doppler Radar at the US Army Proving Grounds, Yuma Arizona. Engineers then created algorithms that utilize both known mathematical ballistic models as well as test specific, tabular data in unison. The software package makes its calculations using the greatest number of variables of any handheld ballistic computer available today and is programmed with all current US sniping cartridges from 5.56 mm to .50 BMG caliber along with numerous other long range rounds.
The system provides the operator with a simple elevation and windage solution through complete integration of external environment, operator, and gun system specifications, enabling small arms weapons operators to produce highly accurate long-range trajectories to any number of specified targets at extreme ranges.
The software package operates on variety of consumer, hardened and mil-spec R-PDA’s running the Windows Mobile 2003 operating system, using input from the Kestrel handheld weather station and a high quality long-range laser rangefinder like the Leica/Vectronics VECTOR Rangefinder Binoculars family.
[edit] Data Tables
Data Tables in print are provided in the event the tactical ballistic computer fails or the batteries for the device fail. This will allow the sniper team to continue their mission by using paper data and a calculator to compensate for the air temperature, air pressure and ammunition temperature.
