The reason for the start of the development of this weapon was the request of US security officials who wanted to get a new sniper system. To perform tasks so-called. police sniper special forces needed a rifle with a set of certain characteristics. The security forces wanted weapons with a range of up to 100-200 meters, the ability to reload quickly, a minimum loudness of a shot and can effectively hit "soft targets." An important requirement of the customer was the possibility of maintaining the pickup after the shot.
The gunsmiths from KAC accepted this challenge and began to study the perspectives of various small arms systems. The requirements relating to the firing range, the striking effect and the loudness of the shot made it possible to quickly and easily identify some of the main features of the new weapon. Other customer requirements, which determined the accuracy and the possibility of making several shots in a row without losing aiming, became a rather serious task, over which I had to break my head.
Probably, the designers of KAC argued in a similar way: the use of vapor or any other automatics that use the energy of powder gases reduces the accuracy of firing, since the moving parts of the weapon begin to shift even before the bullet leaves the barrel. Manual reload, in turn, does not provide the required rate of fire. The only suitable system in this case turned out to be a revolving. She allowed to provide the required rate of fire, as well as eliminate the influence of moving parts of the weapon on the process of a shot. Thanks to the revolving scheme, the new sniper rifle was called Revolver Rifle.
To reduce the volume of the shot were applied several interesting ideas. The barrel rifle equipped with an integrated silencer expansion type. However, the use of a revolving drum threatened to break the gas through the junction of the barrel and chamber. To solve this problem, a new cartridge based on the standard .44 Magnum ammunition was created. According to reports, this cartridge was proposed to equip with gunpowder, giving the lowest possible flash. In addition, in the cartridge was used a scheme with so-called. locking the powder gases: at the moment of the shot, the bullet pushes the special piston-wad, which, after the bullet leaves the cartridge, clogs the neck of the latter and prevents the gases from escaping.
As a basis for the “firing part” of the KAC Revolver Rifle rifle, the Ruger Redhawk revolver was chosen in the version for the .44 Magnum cartridge, which underwent some modifications. Native barrel weapons replaced 10-inch (254 mm). Since the rifle's bullet had an initial speed of about 300 m / s, the barrel received cuts with a pitch of just 9 inches (228,6 mm). Such steep grooves were made to ensure the necessary speed of rotation of the bullet in flight.
A relatively long multi-chamber silencer when assembling weapons was mounted on the barrel and fixed with the help of fixings in the breech. In the rear of the muffler there was room for the trunk, which reached approximately to its middle. In front of the silencer, there were partitions designed to further reduce shot noise.
It should be noted that the available descriptions of the KAC Revolver Rifle rifle raise some questions. The fact is that the simultaneous use of a cartridge with gas locking and a multi-chamber silencer looks like an excess measure. Silencers of this type are designed to hold and gradually cool the powder gases, and in a sniper rifle from Knight's Armament Co. combustion products of the propellant remained inside the liner. The reasons for such a strange feature of the weapon are unknown. Perhaps there is some kind of error in the available tool descriptions.
The revolver retained a six-chamber drum and single-action firing mechanism with a characteristic protruding trigger. The handle of the revolver received attachments for the butt. Under the barrel attached handguard. The stock and handguard were made of plastic. For ease of use rifle on the forearm were attachments for folding bipod. Above the drum and barrel there were mounts for sights. According to reports, the optical Leupold Vari-X was proposed as the main sight, which, if necessary, could be complemented with a Simrad KN 250 night vision device. There was also an open sight mounted above the drum and a front sight on the muzzle of the muffler.
The weapon turned out relatively compact and light. The length of the assembled rifle was equal to 36,5 inches (927,1 mm), weight - 8,5 pounds (3,8 kg). At the same time, the weapon made it possible to reliably hit targets at ranges up to 200 meters. The rifle was supplied unassembled in a special case, which made it possible to conveniently transport weapons and quickly prepare them for use.
The layout of the elements of the rifle in the case
During the tests on the 100 range, several shots were placed in a circle with a diameter of no more than 2 inches (about 5 cm). Interesting results showed noise measurement weapons. The total volume of the shot, when measured in close proximity, did not exceed 119 dB. In this case, the loudness of the hammer strike in an unloaded weapon was 112 dB, and the muzzle wave produced no more than 7 dB noise. Thus, at a distance of several tens of meters, the sound of a shot was almost indistinguishable, and the absence of a flash completely hid the position of the shooter.
KAC Revolver Rifle revolving sniper rifle was developed by order of American intelligence services, because of which many aspects of this project are still unknown. For this reason, there is no information about the purchase of a rifle by police or military special forces, and even more about the facts of its use. In the mid-nineties, the KAC Revolver Rifle rifle reached the civilian arms market. A number of such systems have expanded the collection of lovers of small arms.
The KAC Revolver Riffle sniper rifle was based on a number of technical solutions that are almost not found in modern small arms of this class. Nevertheless, it was the original approach to the creation of weapons that allowed the designers of Knight's Armament Co. develop an interesting sample that fully meets the requirements of the customer. As for the secrecy of some information about this rifle, it can be considered as a kind of confirmation of the effectiveness and success of the development. The lack of public information can speak about the active use of the KAC Revolver Riffle rifle in various secret operations that will be declassified only in the future.
