Action and trigger mechanisms

Manufacture of actions


Orsis rifles are equipped with bolt-action, which is considered the most suitable action mechanism for high-precision firearms. Bolt-actions with two locking lugs are installed on ORSIS SE rifles with barrels produced by cut rifling method.

Special heavy-duty alloy stainless steel and top-grade coils are used to make the actions. Action blanks are worked on upright 4-axis CNC machining centers, conventional lathes with CNC and electro-erosion machine tools. The process involves using special devices with a high-grade Russian and foreign-made cutting tool (from Sweden, Germany, Switzerland and Israel).


Complete metrological control is carried out after each operation to check for deviations from the benchmark values, and only after this can the next stage of processing be carried out. Durability and resistance to impact stress, as well as the precision of fabricated elements – these are all prerequisites for the quality of actions installed in all ORSIS rifle models.

How trigger mechanisms are made

The trigger mechanism is something like a lock to the firing pin. Although this device looks simple, there are numerous demands for the quality of trigger mechanisms. On the one hand, the device should be as light as possible, while, on the other hand, it must be a reliable mechanism consisting of a large number of small load and pressure bearing parts of the firing pin string. In addition, the design should keep it free from dust and dirt, while allowing the device to be easily cleaned and serviced.


ORSIS rifles are fitted with high-quality hammer-type trigger mechanisms with a hard stainless steel carrying case, inner parts made of “scalpel” steel which has undergone special thermal treatment, a titanium cover and are compliant with all safety, precision, durability and user-friendly requirements made for this device.
