5 DESIGN AND PRINCIPLE OF OPERATION OF RIFLE 5.1 Autoloading hunting rifle Vepr-1V for hunting cartridge.223rem (5,56х45) consists of the following assembly units (fig. 3). Arranged on the receiver is the base for fastening the mount of the optical sight. To improve the rifle durability and corrosion-resistance the barrel bore and chamber are chrome-plated. The rifle is reloaded automatically due to the energy of the powder gases, escaping from the barrel bore to the gas cylinder during firing and the energy of the return spring. The barrel bore is locked by two locking lugs while the bolt turning around its axis by means of the sliding bolt support. The trigger and firing mechanism of a hammer type makes it possible to fire a single shot and set the rifle at a safe. Arranged in the receiver is the blocking device that doesn t allow to deliver firing from the rifle with the butt folded. 9
ATTENTION! IT IS PROHIBITED TO FOLD THE BUTT WHEN SETTING THE SAFETY LOCK INTO THE FIRE POSITION. The optical sight is installed on the mount, construction of which makes it possible to deliver the fire with open sight without detaching the scope. The iron sighting device and an optical sight make it possible to deliver an aimed fire at the ranges of up to 300 m. Attached to the mount is the optical sight construction of which makes it possible to deliver firing with an open sight in place. 5.2 Operation principle of rifle When the bolt carrier together with the bolt moves forward under the action of recoil spring, the cartridge from the magazine is being sent to the chamber. When the bolt is being turned, the barrel bore is locked, the hammer gets engaged with the hook of the trigger, the extractor snaps behind the rim of the cartridge-case. When the trigger is pulled, the hammer released by the hook of the trigger and pushed by its spring rotates and hits the firing pin causing the fire. 10
During recoil of the bolt carrier together with the bolt backwards due to the energy of powder gases the barrel bore is unlocked, the case leaves the chamber and interacting with the reflector lug ejects from the receiver, the hammer turns about and gets engaged with sear. When the trigger is released, the hammer snaps from the sear on the hook of the trigger. When the trigger is pressed once again the fire occurs. During counterrecoil of the bolt carrier the cycle is repeated. 6 SAFETY PRECAUTIONS The rifle design provides functioning safety when using hunting cartridges.223 Rem (5,56х45) and its proper operation.

When cleaning is impossible, it is necessary to lubricate the barrel bore with cartridge chamber, the inner part of the gas chamber and the rod with lubricant «РЖ» and clean not later than 24 hours. 9.2.2 In winter, cleaning is performed in the closed premises, where 21
the tº of the ambient air is 20±5ºC. Prior to cleaning the rifle in the room, the rifle should be heated to the temperature in the room. When cleaning the barrel bore and chamber, it is necessary to use clean wiping material (rags, tow cleared of boon) free of sand and hard abrasive particles. 9.2.3 Cleaning is performed in the following order: - lubricate the barrel bore and cartridge box by the slush brush, moistened in the lubricant РЖ, ВО or KPM (see the table 1); - wipe the barrel bore dry by the scourer with a wiping material wound tight round it; - repeat the process of lubrication and cleaning 8-10 times till full removal of the scale (is checked by visual inspection of the barrel bore; the wiping material should be clean); - remove fouling from the gas chamber, piston and bolt carrier rod; - after cleaning, lubricate all the parts and mechanisms of the rifle with clean lubricant РЖ, BO or KPM. 22
Table 1 Lubricating materials When the temperature from 273 to 223 K (from 0 to -50ºC Rifle lubricant РЖ Rifle lubricant KPM When the temperature from 273 to 323 K (from 0 to +50ºC) Rifle lubricant РЖ or BO Rifle lubricant KPM Points to be lubricated The barrel bore The bolt, bolt carrier, guides of the receiver, magazine Method of applying lubricating materials Lubricate the barrel bore by bore brush from the side of the muzzle end having moistened the bore brush beforehand in the rifle lubricant (2-3 double cleaning rod stroke along the all barrel length). Wipe the parts by rags moistened beforehand in the rifle lubricant and wrung. 23
It is necessary to perform lubrication depending on the temperature conditions according to the table 1. It is inadmissible getting thick of the lubricant in the bolt hole under the firing pin, in the socket under the extractor and on the mainspring. 9.3 Zeroing the rifle with use of the iron sighting device When it is necessary, adjustment of firing precision is performed by travel of the foresight base to the right-and-left and by rotation of the foresight up-and-down. When shifting the foresight base by 1 mm, the mean point of impact travels by 200 mm. One full turn of the foresight moves the mean point of impact by 150 mm. Ranging is conducted at a distance of 100 m. 9.4 Zeroing the rifle with use of the optical sight The optical sight is zeroed by firing at a range of 100 m, the drum scales are set at division 0. In case of unsatisfactory results of test firing, verify the optical sight with use of the iron sighting device, for which purpose: - set the slide of the iron sighting device at division 1 of the sight leaf; 24
- put the rifle on a support and lay it on the reference point of the target which is at the distance of 100 m; - check the position of the optical sight sighting sign relative to the aiming point, if they do not coincide, it is necessary to match them by rotation of knobs not shifting the rifle; - check the adjustment by firing. If it is necessary to zero the optical sight at the other ranges, zeroing should be performed by rotation of the range drum. Apply the marks which correspond to the ranges on the range scale against the indicator and the scale point meanings enter the table 2. Table 2 Range, m 100 200 300 Scale points 25
9.5 Maintenance in Storage To keep the rifle in a ready-to-fire condition it should be always cleaned and lubricated with a thin layer of rifle grease. The rifle should be stored in the dry premises without sharp fluctuation of the temperature, far from heating devices and free of aggressive admixtures in the ambient air. To avoid appearance of the residual deformation the trigger should be pulled. 26
