What is the stopping power, "Brother"?

The domestic arms company ORSIS has shown the world a 7.62x51 self-loading carbine with a 10-round magazine. For the first time it was demonstrated at the arms exhibition "ARMS and Hunting 2017" in Moscow. Then began his triumphal procession in the country and abroad. In particular, this spring it was presented in Delhi and Nuremberg. True, the carbine was not yet in mass production.

Officially, it is called ORSIS-K15, but in everyday life it was nicknamed "Brother."

Manufacturers position the novelty exclusively as a hunting or sporting weapon. However, the security forces have already shown keen interest in him.

Endurance "Brother" - the envy of the Mosin rifle, he is able to work in the temperature range from +50 to -50 degrees Celsius. In addition, various weather problems such as rain, snow, mud or sand in the trigger will not interfere with the shooting.

Despite the fact that the metal structures of the carbine are made of aluminum alloys and high-strength structural steels, its mass does not exceed 5 kg. In general, it is not the easiest in its class. However, experts say that a large mass will reduce the return.

The carbine was created as an answer to the quite successful semi-automatic rifle AR-15, developed in the USA. However, there are many categorical differences. First of all caliber: American rifle - 5.56x45, Russian carbine - 7.62x51. In addition, the carbine uses a two-position gas regulator. And the use of a gas engine with a short piston stroke makes it faster.

Locking the bolt of the ORSIS-K15 carbine is carried out with a twist on two lugs, while the design provides a rigid reflection of the spent case.

By the way, the design allows you to adapt the carabiner for both left-handers and right-handers. In particular, the handle for reloading weapons can be installed, both on the left and on the right. As in many rifle types of weapons of this type, the Brother has a Picatinny-type rail for mounting scopes and a tactical body kit.

But the main innovation of the new rifle system is the processing of the barrel. When creating it, the old reliable Soviet single pass threading method was used. According to experts, this will allow to obtain almost perfect geometry of the bore, which will improve the accuracy of the impact, as well as accuracy.

By the way, as for accuracy, at a distance of 100 meters it does not exceed one angular minute. That is, if you shoot at the "ten" from a given distance, then the diameter of the holes between the prepared shooter will be 2.9 centimeters.

As already noted, the carbine is made in two versions: hunting and sports. In sports, the length of the trunk will be 405 mm, in hunting - 508. In both cases, the effective firing range is the same and is 800 meters. Number of rifles - 4. Replacement of the butt and installation of bipods is possible.

In the military version, it will be possible to increase the number of rifling and extend the barrel to increase the effective range of the shot and the accuracy of the hit. However, this is a completely different story.
