The SV-98 sniper rifle was developed by the Chief Designer Department of Concern Izhmash, a group of authors under the leadership of Vladimir Stronsky, based on the Record-CISM 7.62 rifle sports rifle. Sizm. "
The SV-98 is designed to defeat enemy forces that appear, move, open and unmasked, unprotected and equipped with individual armor protection at a distance of up to 1000 m.
CB-98 is a non-automatic magazine rifle, designed according to the classical layout.
The barrel together with the chamber is made by horizontal cold forging from a single piece. The trunk CB-98 is cold-faced with the latest technology in the GFM machines of an Austrian company from the city of Steyr. The whole forging process is controlled by a program from a computer. Even the formulation of the barrel billet and the removal of the barrel is carried out automatically by a robot. After forging and the necessary shutter speed (the barrel must “settle” to relieve the intracrystalline stresses created during forging), the barrel bore is honed, and only then goes to heat treatment. The barrel channel is not chrome-plated, which, although it reduces its survivability, but it significantly increases the accuracy of fire - ranging from 60 to 70 mm when shooting groups of 10 shots at 300 meters. The barrel connects to a rectangular box with four pins. This whole structure is attached to the cradle with two screws. At the same time, the barrel remains freely hung out. A floating barrel is a common solution for high precision weapons. On the trunk there is a mounting point muzzle brake or muffler. Trigger pull adjustable.
Muzzle can be equipped with a silencer. If this is not necessary, a protective sleeve is wrapped around the barrel. The peculiarity of this seemingly unusual sleeve is that, due to the peculiarity of the thread, it creates a certain tension on the muzzle, which improves the accuracy of the fire. Accuracy, by the way, improves when using a silencer. Alternatively, both the silencer and the sleeve can be fitted with a flame arrester. The silencer is designed to reduce the level of sniper unmasking, complete suppression of the muzzle flame. It is also important that the silencer does not impair the accuracy of shooting and reduces the recoil energy by about 30%, which makes rifle shooting more comfortable.
The bolt has three lugs. The trigger mechanism of the sports type, with adjustable triggering effort. The CB-98 fuse is a two-position, located in the receiver, closer to its tail, on the right side, behind the bolt handle. It blocks both USM and the stroke at the same time. Type of fire - single. Recharge manual.
The power is supplied from the box-shaped detachable 10-local shop, on its left wall there are holes with markings, by which the sniper can determine the number of ammunition at his disposal. The store has a guiding mechanism that facilitates its adjunction in a combat situation and "in the blind." The course of the store is straight, and not like that of the SVD with a turn from the hook to the side of the latch. Shop rifle double row, molded from glass-filled polyamide with metal liners. The customary prismatic or lamellar spring is replaced by a lever element consisting of 4's levers interconnected by axes in pairs in the center. Store in front of the rack is mounted, which is pressed into the receiver. In the rack, a latch with a spring is mounted, which, when the magazine is attached, engages with a metal sleeve, which is fed into the opening of the magazine case and presses the magazine tightly to the receiver. Thus, it provides a simple, stable and secure mounting magazine on a rifle.
The rifle is regularly equipped with open sights - the front sight in the earpiece and fully adjustable. Fly (adjustable vertically and horizontally) and open type rear sight with a scale of distances from 100 to 600 m. In increments every 100 m. The base of the front sight is the original design, but the front sight itself and the rear sighting device are fully borrowed from the SVD. However, unlike the Dragunov rifle, the SV-98 has a different system for mounting an optical sight. In CB-98, the sight is mounted directly on top of the box with the help of a device commonly known as dovetail. The box bears on itself the top assembly level for sights. It can be 7-multiple PKS-07, and more powerful pancratic "Hyperon", worked out according to the scheme 3-10 XX42. For night operations on the rifle put a whole range of night vision devices.
The forearm of the CB-98 rifle has two oblong ventilation holes. Pistol grip made with a notch. The stock is fully adjustable and tailored to the individual ergonomic data of the shooter. For this, a lifting cheek and a movable butt plate are provided. The rifle is equipped with an adjustable wooden lodge (the position of the butt plate on the butt and the position of the stop under the cheek are adjusted). In front of the box there is a mount for folding bipod.
Sniper rifle CB-98 developed for different types of ammunition, both domestic and foreign manufacturers.
The standard equipment of a rifle includes a low-noise firing device (PMS), a belt and a carrying handle, an anti-strap belt and a visor-reflector on a silencer, a set of accessories for cleaning and an optical sight bracket.
There is a version of the rifle with the popular in the world and which is the standard of NATO, the Piccatini bar, also called "Weaver rail" ("wr" - "Weaver Guide").
The rifle has high accuracy, good steady accuracy. At a distance of 300, m sets up groups of 10 shots in each (cartridges not lower than the Extra class) in a circle with a diameter of 55 mm. A regular sniper cartridge shooter easily puts all shots in a circle with a diameter of 120-130 mm on 300 m. An experienced sniper is able to hit a growth target at a distance of up to 1200m from the first shot.
Sniper rifle CB-98 passed all certification tests, was used in real combat operations and is in service with the special forces of the Ministry of Justice, the Ministry of Internal Affairs, the FSB - where high precision fire is required.
