Perst-4 is used to point targets when observing , inspecting and watching small arms shooting at night. This product is a small optical mechanical device that forms laser radiation flux. This product is installed on Picatinny rails. The KV-D2 Tactical switch (in the kit)can be installed on picatinny rails and 1913 rails. Perst-4 contains 2 laser functions:
Green Laser light source: wavelength - 635 nm
IR laser source: wavelength - 850 nm
Power supply: CR123A (No Included)
Effective range in the dark:
Green beam: 300 ± 100 m.;
IR beam: 400 ± 100 m.
Overall dimensions: (37х60х91) ± 3 mm.
1. The triangular area on the host can switch between visible laser and IR
2. On the top or side of the host , the round switch is turned on. Turn on through the KV-1P Wire Control Switch
3. Two small circular buttons on the main unit to adjust the laser brightness .
Fit For: 20mm Picatinny Rail
