Sights for firearms

Rifles and shotguns

— sights designed for firearms with low or medium shot energy — primarily rifles of small and standard calibers, as well as shotguns (shotguns) in caliber up to 12 inclusive.

The design of such sights allows them to endure rather strong shocks and vibrations that occur during recoil without consequences. At the same time, specific restrictions on muzzle energy can be different — accordingly, the possibilities for working with certain calibers differ. For example, an intermediate caliber .223 (up to 1800 J) or 7.62x39 (up to 2200 J) is easily tolerated by almost all similar sights, but the possibility of using it with rifle .308 (up to 3700 J) and 7.62x52R (up to 4100 J) it doesn't hurt to clarify separately, especially if you plan to use reinforced ammo. And some calibers, formally related to standard ones, can give muzzle energy much higher than 4000 J, and they already need sights of a more serious “weight category”. The situation is similar with shotguns: a standard cartridge with a regular weight of gunpowder will certainly not create problems, but reinforced ammunition, especially with an elongated cartridge case (for example, 12x76), may be too powerful for a scope from this group.

Separately, it is worth touching on the installation of such sights on pneumatics. With powerful PCP models, they can be used without restrictions, however, oddly enough, problems can arise with "airs" that have a spring-piston mechanism. The fact is that such rifles give a specific return, directed forward rather than backward, moreover, giving sharp fluctuations in different directions; and although the force of such recoil is low, it can still adversely affect the sight, which was not originally designed for it.
