5. Disassembly of a sniper rifle can be incomplete or complete: incomplete - for cleaning, lubricating and inspecting the rifle; full - for cleaning when the rifle is heavily soiled, after being in the rain or snow, when switching to a new lubricant and during repairs. Frequent disassembly of the rifle is not allowed, as it accelerates the wear of parts and mechanisms.
Disassembly and assembly of the rifle should be done on a table or clean mat; Place parts and mechanisms in the order of disassembly, handle them carefully, do not place one part on top of another, and do not use excessive force or sharp blows. When assembling a rifle, compare the numbers on its parts: the numbers on the receiver must correspond to the numbers on the bolt frame, bolt, trigger mechanism, receiver cover, optical sight and other parts of the rifle. Training in disassembly and assembly on combat rifles is permitted only in exceptional cases with special care when handling parts and mechanisms.
The procedure for incomplete disassembly of a sniper rifle.
1) Separate the store.
Take the magazine with your right hand, pressing the latch with your thumb (Fig. 3), move the lower part of the magazine forward and separate it.
After this, check if there is a cartridge in the chamber
, to do this, lower the safety down, move the charging handle back, inspect the chamber and release the handle.

General information about IZH-61
The bottom line is this: this is a cheap spring-piston rifle, for which craftsmen have already developed a ton of upgrade options. It shoots small bullets of 4.5 mm caliber, or otherwise designated as cal .177, you can’t shoot balls from it!
What is also interesting about the rifle is the variety of appearance that the tuners strive for: here is the VSS, and the AK-47, and in general, anything else. Feel like a stalker))
The bullet speed is approximately 130 m/s, the rifle power is up to 7.5 Joules.
As of June 2014, the cost of the IZH-61 rifle is approximately 3,500 - 4,500 rubles. depending on the store. In my native Cherepovets, I bought it in the Kombat store on Parkovaya, 7 (it’s behind the church, not far from the beach). In general, in our local stores the price tag looks like this: “Robinson” - 4,800, “Weapon” - 4,530, “Combat” - 4,200, “Khaki” - no, “Soldier of Fortune” - no.
This rifle out of the box is practically not intended for anything other than training. Shooting at living creatures (such as crows, pigeons, etc.) will most likely lead to wounded birds and animals suffering from the new “hunter”, since the power of the rifle is not enough to guarantee the killing of a bird or animal.

Bullets for IZH-61
3. You need bullets. The bullets cost me about 250 rubles. per package. I took GAMO Master Point and GAMO Hunter. Why are they like this? Firstly, some are pointed, others are blunt - I’ll see what the difference is, and secondly - what difference does it make which one to take for the first time...
