The PK-AA is a rather modern red dot sight by BelOMO.
It became known as the PK-A Venezuela in the English-speaking world after a big sale to Venezuela in 2001.
Right off the bat, you will notice that the sight is labeled as PK-A. However the actual designation given by BelOMO (БелОМО) is PK-AA (РК-АА – so actually it should be called RK-AA in English). This could be another reason why it is known as PK-A Venezuela in the English-speaking world.
Even so, the PK-AA has little to none in common with the PK-A. Although it might appear somewhat similar in its general shape, technically it is a completely new sight.
While the PK-A was clearly developed from the PSO-1 series, the PK-AA has a competently new body and lens systems. Also the light emitting diode and the according adjustment knobs are placed totally different compared to the PK-A.
Weighing in at about 600g, it is no a light sight. On the other hand it is build like a tank, like most Belorussian/Russian military optics.
Speaking of the brightness: The steps are larger then you are used to with Russian red dots – and that is a good thing. On the lowest/lower levels you can use it with night vision googles (tested it with gen1, and gen3). On the contrary, the dot is extremely bright on the highest level. Prior sights often lacked that ‘feature’.
According to most/all re-sellers on the internet, the size of the dot is 1 MOA. I would argue that it is in fact somewhere around 1.5-2 MOA. Unfortunately it is not mentioned in the manual either.
The battery lifetime has been greatly improved also. This is partly due to the use of an
AA battery, I suppose that is also where the designation PK-AA originated from, but also by using more modern electronics.
It is still no Aimpoint in that regard, but it is a sight that you can leave switched on for months.
Depending on the brightness level, the batteries and of course the temperature, it will run 5-6 months straight.
The rubber covers can be folded into each other so that they do not swing around and disturb you.
The front lens is coated to improve the contrast. The coating looks pretty heavy on the photo, but actually it is not that bad. You won’t necessarily need a kill-flash, like it is the case with some of the excessively coated optics.
The adjustment knobs are hidden under waterproof screw-caps. I am pretty sure, that the adjustment knobs themselves are waterproof also. So you if you prefer the adjustment knobs to be instantly accessible, you could just leave them off.
Off course every sight has its unique serial number, which can also see on the photo above.
As one can see on the photo above, the sight sits pretty low. However it just barley
co-witnesses. So using iron sights is possible, but the red dot will very close to the lower edge.
The PK01-V is much better in that regard.
There is another difference to the PK-A, which I have not mentioned yet. The PK-AA uses the ‘BelOMO locking mechanism’, while the one on the PK-A is of the ‘SVD style’.
What I refer to as the ‘BelOMO locking mechanism’, is simply the mount-base that BelOMO basically uses on most of their more recent products.
As to be expected the sight comes with a pouch, a manual/warranty, some cleaning tools and a small laminated leaflet.
According to the manual, mine was manufactured in 2013. That proof, that the myth of them being just surplus/leftovers after the deal with Venezuela is wrong!
I assume soldiers were supposed to keep the leaflet with them as a reminder how to adjust and work with the PK-AA. One can see how the 400m zero concept, that has been established with the 5.45x39mm round and later carried over to a 300m zero for 7.62x39mm, is reflected in the graphics.
The ‘first’ side explains how to zero your sight. Depending on the caliber (it is explained for 7.62×39 / 5.45×39) one has to pre-adjust the sight. You are supposed to shoot a group tighter then 7.5cm / 5cm at 100m. Once one is on target with the adjustments (a click is 2cm at 100m), the pre-adjustments need to be reversed in order to change the zeroing from 100m to 300m / 400m.
On the other side it shows the ballistic curve for 7.62×39 / 5.45×39 – or for the AKM&AK-103 / AK74N to be precise.
For example, the round will actually hit 34cm / 40cm above the target at its highest point in the trajectory, which is at 162m / 217m. It is also interesting to see how fast 7.62×39 looses its energy. While one would be spot on at 300m, only 50m further the round will hit 77cm low. They did not even bother to give an estimation for 400m – that really shows the limitation of that caliber.
