Large-caliber sniper rifle THOR M408
The new THOR M408 sniper rifle was introduced by the THOR Global Defense Group at the start of 2010. This rifle was a further improvement of the CheyTac M200 large-bore sniper rifle, the production of which was completed in the first decade of the 21st century. Rifles combined a single cartridge 408 Chey Tac caliber 10,3x77 mm. The bullet of this cartridge is able to hit any body armor, as well as concrete slabs, walls, lightly armored vehicles. The cartridge is designed for use with sniper complexes, it provides a high-precision level of fire, is in service with security forces, and can be used as an anti-sniper and antimaterial weapon in combination with the THOR M408.
In the THOR M408 large-caliber sniper rifle, manual reloading is used with a longitudinal sliding bolt and also with two lugs located in front of the bolt. To increase the reliability of the use of weapons in the most adverse weather conditions, the valleys (longitudinal grooves) of the spiral shape were cut on the surface of the bolt. These grooves were designed to squeeze out dust and dirt, and also had to prevent the movement of the shutter. The barrel of a rifle is thick-walled, massive enough, it is equipped with an integrated muzzle brake-compensator. The barrel also has longitudinal valleys, they are cut through its outer surface and serve to increase the rigidity of the structure, better cool the barrel and reduce the overall weight of the sniper rifle.
The receiver of the rifle is made of steel, it has a massive structure in which a quick-change barrel is installed, placed in a special tubular forearm-casing. In the muzzle of the barrel has a thread that is designed for mounting the muzzle brake-compensator or silencer sound of a shot. Above the trigger on the right side of the receiver is a two-way fuse. The sniper rifle is supplied with ammunition from detachable box magazines designed for 7 cartridges of caliber 10,3x77 mm.
This sniper rifle is not staffed with open sights. For mounting optical sights on it are common guide rails type Picatinny rail, which are located on the receiver. The weapon manufacturer recommends using the Nightforce 5.5-22x56 optical scope with it. If necessary, the optical sight can be supplemented with an infrared laser for target illumination and a night vision module.
One of the features of the THOR M408 large-caliber rifle is its retractable telescopic butt, which has an adjustable cheek and a folding adjustable back support under the butt. It is the original telescopic butt with the “third leg” in the back and the pistol grip that complete the overall picture. The advantage of this butt is the ability to reduce the overall length of the weapon, and the minus is that the pillow under the sniper’s cheekbone is unregulated, and in addition, the butt looks flimsy, as it is attached to a rifle on rods of small section. The butt plate was equipped with a special rubber insert, which is able to extinguish the recoil force and increases the comfort of using the weapon for the shooter. In front of the forearm (barrel cover) a folding bipod is attached to the rifle.
For the convenience of carrying a THOR M408 sniper rifle in a combat situation, it has a rotary handle that is located near its center of gravity. For transportation in the stowed position and storage of weapons, the barrel is removed, and the telescopic butt slide moves forward to the stop, which significantly reduces the size of the weapon.
In the basic version and with correctly selected cartridges, a large-caliber THOR M408 sniper rifle is able to provide stable accuracy of shooting with a rate of less than 1 angular minutes (Sub-MOA) at a distance of 2000 yards (1829 meters). Large-caliber sniper rifle THOR M408 is in service with the armed forces of the United States and a number of law enforcement agencies. It is also represented in the civilian market, it is in demand among shooters who are engaged in high-precision long-range shooting.
The THOR M408 rifle is used with a .408 Cheyenne Tactical large-caliber cartridge, commonly referred to as the 408 Chey Tac. This munition was created in 2001 by employees of the American weapons company CheyTac USA. Initially, this cartridge was conceived as a special sniper cartridge of the XXI century. It was designed to provide high-precision shooting at long distances up to 3 thousands of meters, while maintaining the destructive power of the bullet at a distance of up to 3,5 thousands of meters.
However, despite such impressive numbers, in reality, the .408 Chey Tac 10,3х77 mm cartridge is used at a distance of up to 2,5 thousand meters. This limitation is due to the technical capabilities of today's large-caliber sniper rifles, as well as the sighting devices used with them. In the line of sniper ammunition, this cartridge occupies an intermediate position between the very popular .338 Lapua Magnum cartridge (8,6х70 mm) and the very powerful .50 BMG (12,7х99 mm). At the same time .408 Chey Tac is only slightly inferior to the latter in terms of killer action. At the same time, it slightly exceeds the .50 BMG cartridge in terms of external ballistic characteristics at a shooting distance of up to 1000 meters, while possessing a significantly lower return at the moment of the shot.
