Before the operation of any small arms, it is necessary to determine its characteristics. You can deal with this with the help of the zeroing procedure. Performing it manually, it is impossible to get accurate results. Therefore, today a special machine for shooting weapons is widely used by professional military men, hunters and lovers of guns and pistols. This device is now also used to train personnel of the armed forces of many countries of the world.
What is a sighting machine?
The product is a special device that allows rotation when aiming a fixed small arms. Many weapon manufacturers also sell these systems.
Despiteon a variety of models, any sighting machine performs one function: with the help of a rigid base, it securely mounts the weapon, eliminating any impact on it from human and weather factors.
What are the machines?
Depending on the functions performed and design features, the sighting device can be:
- Collapsible. One such product is the Benchmaster Shooting Tab. The set consists of a table and a chair, which can be easily disassembled if necessary. This machine allows you to sight the carbine in a sitting position.
- Stationary.
- Universal.
- Specialized, i.e. designed for certain types of weapons. Mostly on such devices, air rifles are sighted. A feature of such machines is their low weight.
- Intended for zeroing only.
- Used in gun maintenance.
What determines the cost of the machine?
Prices for sighting devices vary. The cost is affected by the brand, size, weight and material from which the product is made. The best and most reliable is the model that is able to provide a rigid fixation of small arms on any surface. Therefore, such a machine is more expensive. The cost of the product is also affected by the mechanism in it, which determines the height of the installation of the barrel. Each machine model can also be used as a gun cleaning stand.
Bwhat is the point of shooting?
The task of this event is to combine the point of average hits of the weapon with the sight of the target. It can also be the crosshairs of optical sights.
In progress:
- sighting the scope;
- determined by the accuracy of hits;
- selection of a certain type of bullets.
It is desirable to carry out zeroing in a shooting range - a closed room in which the influence of wind is excluded. The essence of the work lies in the reliable fastening of small arms in the machine and the subsequent shot at a certain distance to the target. The carbine located on the frame is aimed at the target with special regulating elements. The weapon fixed in the machine acts as an easel machine gun.
The end result of good zeroing is for the shooter to find the mid-point of impact after several shots. After that, by tightening the flywheels, the aiming mark is combined with the hole in the target formed after the shot.
When are machines used?
Zeroing for a carbine or shotgun is required:
- if new small arms are purchased;
- as a result of drying out of the wooden bed;
- when replacing optical sights;
- if the owner decided to change ammunition;
- if the weapon was stored for a long time without a case or was transported;
- after intensive use.
Also, those guns andcarabiners, to which recoil compensators and muzzle devices are mounted. It is advisable to use sighting machines on weapons that have been dropped.
For DIYers
Is it possible to make a machine for shooting a carbine with your own hands? This question interests many.
Today, purchasing such a device is not a problem. Despite the fact that these products can be found in special stores, many owners of small arms prefer to make them themselves using various improvised means: pillows, shelves, plywood and stools. These things are used as stands for small arms. The disadvantage of such devices is their unsteadiness, which interferes with the shooter, excluding the main purpose of the work performed. In addition, the zeroing process itself can drag on for a long time, which is fraught with high ammunition costs. High-quality sighting is possible only if the shooting position is thoroughly equipped. Setting up the weapon in a comfortable environment for the shooter (the complete absence of any external influence on the carbine) will save ammo.
About drawings
If you have the necessary materials and tools, it will not be difficult for a craftsman to make a machine for shooting a carbine with his own hands. Drawings of such devices are of interest to many who want to facilitate the process of creating a sighting structure. During the manufacture of the machine, the master can perform complex turning, milling and welding work. The process can be greatly simplifiedhaving created a do-it-yourself machine for shooting a carbine from a metal pipe. Design drawings by craftsmen are mainly replaced by generous publications of photos of the finished device, recommendations regarding its manufacture and description of the technology. Or they are offered for purchase on the Internet, subject to a significant advance payment. Therefore, they are a kind of deficit, very popular in networks.
What material do you need to work?
To make a do-it-yourself carbine sighting machine, the craftsman will need the following materials:
- Steel pipe with rectangular or square section.
- A stud with a thread diameter of 14 mm.
- Bolts (3 pcs.). The diameter of two should be 14 mm, length - 100 mm. Third bolt with a length of 150 mm.
- Bolts with nipple nuts (6 pcs.). The diameter must be 5mm.
- Several bolts - rivets.
- Regular nuts and washers.
- Metal plate 6.5x8 cm.
- Corners (3 pieces) size 5.5x6.5 cm.
- Spray paint.
Which tool to work with?
You can make a machine for shooting a carbine with your own hands using the following inventory:
- angle grinder (grinder);
- electric or hand drill;
- screwdriver set.
Steps of work
- Cut a metal pipe in such a way that two pieces are obtained, 700 and 400 mm long.
- Ground the burrs in the resulting pipe sections.
- In order to prevent deformation, you need toinsert wooden beams into the ends of two pieces of pipe.
- Cut the hairpin into two pieces 400 mm long and chamfer them.
- Two holes must be drilled in the pipe section (700 mm). Their indentation from the edge of the metal piece should be 20 mm.
- Drill four holes in the piece (400 mm). Two of them should be 20mm from the ends of the pipe (as with the larger piece) and the two holes between them should be 150mm apart.
- Using a bolt, connect the long and short segments with corners. Between them, in order to prevent erasing of paint, it is recommended to place washers. Its presence will preserve the colorful coating of the machine in cases where it is folded. A wing nut is used to fasten the bolt.
- On a short piece of pipe, you need to install the studs and secure them tightly with nuts. When making a do-it-yourself machine for shooting a carbine, it is very important to pay attention to the reliability of the connections, since the presence of play can adversely affect the accuracy of fire.
- In a short piece of metal in the extreme hole, insert the washer, and then the bolt and wing nut. The presence of a restrictive nut will enable the owner of the machine to adjust it in a horizontal plane.
- Fix with a bolt 150 mm long stop for carabiner. This work is done on a long run. The bolt is installed in the second hole.
What can you make an emphasis out of?
A small sandbag or pillow is ideal for those who decidecreate a do-it-yourself machine for shooting a carbine. The photos below show the design features of such products.
The rubber mat is also good as a stop in a homemade sighting device. This manufacturing method is considered simple. The craftsman will need to cut several pieces of rubber fabric and carefully lay them on the surface of a metal plate in several layers. For fixing, four bolts are used, which fasten the stop parts in the corners and in the center of the steel plate. Bolts are recommended to be inserted from the side of the plate, and furniture drive nuts - from the rubber layer. Thus, the inserted nut will, with the help of its antennae, securely press all the rubber compound stops. It is not recommended to use glue for fastening, as such connections are considered fragile.
When making an emphasis for the machine, you can use an angle grinder (grinder). With its help, the process of processing an already assembled stop will become much faster. Using a grinder, homemade stops are given the necessary shape. At the same time, it is very important to monitor the grinding process, since rubber is a material that is easy to process. The slightest inattention at this stage of work can ruin the product.
How to set the stop on the alignment machine?
The stops and machines differ in their purpose.
Emphasis is an element that is necessary in order for the weapon to roll freely after the shot. The fixation of the forearm is performed by himselfmachine for shooting a carbine. You can make an emphasis with your own hands, using also three corners fixed with buttons. In order to prevent possible damage to the weapon, it is recommended to grind all parts that will come into contact with it. The stop is mounted on a special plate, which will be located on the bolt. His hat is also recommended to be carefully cleaned. With the help of nuts, the height of the stop is adjusted. To facilitate this process, ordinary nuts can be replaced with nuts - "lamb".
Properly made and installed stop will make the operation of the machine comfortable, and the zeroing process itself efficient.
What should a homemade sighting device look like?
Deciding to create a machine for sighting hunting. do-it-yourself carbine, the master must consider:
- In terms of weight, the product must be heavier than the carbine. Otherwise, the resulting vibration will not be extinguished. Some craftsmen use barbell pancakes to add weight to their machines.
- A zeroing machine can be considered correct if it is rigid, and its nodes and connections do not have any backlash.
- In an ideal sighting machine, horizontal and vertical aiming of weapons at the target is performed. A home-made product can be considered universal if it can be used for shooting for various types of weapons: air rifles, hunting carbines, combat and sports pistols.
The bottom of the sighting station must be firmly fixed to the table
Nuances to pay attention to when zeroing in
- In setting up the carbine, you need to use only those cartridges that will later be used by the owner on the hunt. It is undesirable to carry out sighting with sports bullets, since they weigh 9 g, in contrast to 13-gram combat ones. The result during the adjustment of the carbine and the real hunt will differ significantly.
- It is desirable that the owner performs the finishing or final zeroing of the weapon. Several control runs are recommended.
- You need to start the procedure of sighting the carbine from a distance of 50 meters. Gradually, the distance can be increased to 100, 150, 200, 250 and 300 meters.
- During the entire zeroing process, it is important not to change the initial shooting conditions.
- You can zero in with the correct position of the carbine on the machine: the forearm of the weapon on the machine must correspond to the conditional position of the hand without using the sighting structure. Ignoring this aspect and the uneven location of the carbine on the stop can lead to a shift in the points of impact and, as a result, zeroing will be unsuccessful - the fired bullets will constantly miss the target.
- The use of various camouflage materials for small arms can lead to increased dispersion when firing. Any winding of the barrel gives a distortion of the accuracy of hits. This feature of guns and carbines should be taken into account and carried outsighting already with camouflage winding.
