The PK-AS is a versatile, compact and waterproof sight with a rather unique working principle made by BelOMO (БелОМО) in Belarus.
Often people refer to it as reflex sight or red dot, which does no justice to its capabilities at all. Why? Take a look at these two photos:
Compared to a regular reflex sight, like the Aimpoint CompM2/4, the advantages of this design really begin to show:
- Due to the lens system the visible image takes up 100% of the ocular, you can not see the ‘inside’ of the sight
- The black reticle is always visible, the sight can be used without a battery. So there is no need for backup sights either
- The reticle and the red dot will not get bigger when increasing the distance between the ocular and the eye. Very much like on holographic sights by EOTech, though they use laserlight to archive the same effect.
- The elevation adjustment can be change on they fly, to compensate bullet
The reticle consist of a 1 MOA black dot enclosed in a elliptical 170 MOA range-finder circle. As mentioned, it is always visible without the use of battery. A 1.5 MOA red dot can be used on demand.
The sight is powered by two D-357 button batteries for a total of 3V of power. The brightness adjustment knob uses the typical Russian 8 mode off-on-off layout: (0-1-2-3-4-5-6-7-8-0)
As mentioned before the sight can be used without any better. This is a typical feature for most Russian sights. They either use a tritium & solar combination instead of a battery, or will work with an empty battery, since the temperatures in Russian winters are often beyond a point where batteries work.
Often you will see an additional letter at the end of the label. This refers to the mount base which is used:
The original mount for the PK-AS is off-bore to left, the PK-AS-W (which is the one in this review) has a 22mm mount base. The PK-AS-V uses a centered BP-02 based mount. It should be worth mentioning that the sight itself is screwed onto the different mounts, so you can change between these three. I personally only use the W and V mount since I don’t see any benefit in the off-bore mount.
As for now the PK-AS is not adopted by the Russian military, but is in use with the gru und police units. Same goes for Belarus.
