PSU 1x or 4x Magnification - NPZ 

MMW named Vavilov, logo

Imported and labelled by Wolf Performance Ammo (WPA), this is a relatively new optic from NPZ very similar to the Elcan DR optic and clearly intended to perform the same role.

It is a 1x or 4x optic simply called PSU and is not currently in military service that I have seen (2016). While not strictly designed for 5.45x39 the prototype model shown here is calibrated for 5.56x45 M855. As you will see below the reticule pattern is well designed and I believe with a quality mount it will work quite well on any AK pattern rifle including PSLs and Veprs, as well as the SVD. This is why I have included it in both 5.45 and 7.62 optics sections

First impressions of PSU are really good and it appears to be built like a tank. The locking levers are solid and do their job well but are tricky to adjust. Easy enough once you get the hang of them but not so obvious the first time around. It uses the castle nut method of tension on each lever.

I have to say that I really like this optic, though in general I personally do not see a use for the Elcan or any optic that switches between 1 or 4x. In my experience it's better to go with a 1x collimator, a red dot or a dedicated 4x rather than a variable power. Between quick disconnect options and practicing with techniques like the Bindon Aiming Concept I just don't think a 1 or 4x is worth the weight penalty, or the additional expense. Having said that the military community seems to hold the Elcan in high regard and I acknowledge it is a really nice optic, just too heavy IMO for the relative merits of being able to switch between 1 or 4x. Weight is 27 ounces without mount and height over rail to center of ocular is 1.5 inches (compared to 2 inches for Elcan)

However as I said I really like this optic and it will be doing duty on my SVD Tiger rifle mainly because of the reticule pattern. I already really like it and find it an interesting change of pace from the PSO-1

I am still testing this optic and have not verified that the 4x zero aligns with the 1x POI but hope to get that settled soon. Overall I personally enjoy this optic and would like to recommend it but frankly do not think it is worth the price ($1300 as of 2016). Also there is no question in my mind the Elcan is a superior optic but it is also considerably more expensive.
