Air rifles without scope
Is absent
— the absence of any sighting devices in the original delivery set — there are only mounts for installing such devices.As fasteners, dovetail-type straps are usually used, less often — Weaver / Picatinny rails (for each of these varieties, see "Additional"). But in general, such equipment does not allow the use of a rifle “out of the box”, however, it makes it possible to choose a sight for it at your discretion, without relying on the choice of the manufacturer. This is especially true if you plan to use optics — nowadays a wide variety of such sights are produced for different tasks and usage scenarios. Actually, most air rifles without a scope are designed just for the installation of optics, although the possibility of using collimators is often also allowed; and in airsoft pneumatics, removable front sights with rear sights are also used.
Also note that spring-piston rifles and models with a gas piston (see "Type") have a specific double recoil, which not every sight is able to transfer — even if it allows use with powerful firearms. Therefore, when looking for optics or a collimator for such pneumatics, you should be especially careful — for it you need to choose sights that were originally designed for such rifles.
