PK01-VS is an extremely low and centerline red dot
that cowitnesses when the rear sight leaf is set on 1.
This is a BelOMO/LEMT optic that had been submitted
for military evaluation but in 2012-2013 it was not
known if it has entered serial production.
The original two examples in the USA were overruns
from the original batch submitted to the military, and
in 2013 there was one photo of the VS being used in
the recent Libyan uprising.
As of late 2014 it appears that PK01-VS has
entered production at last and is now available in
After having used this optic on the AK105 for some time now I have to say this is hands down my favorite red dot, followed by the PKA-Venezuela. Both have extraordinary battery life at 3600 hours for VS and 3700 for Venezuela, both have absolute cowitness on an AK and both are built like tanks. VS is much lighter than Venezuela and so of the two I recommend VS if possible, but Venezuela is definitely a robust and well made optic.
In my opinion VS is the best of the "combloc" tube based red dots on the market. Other than the ultra rare OKP-7, VS is the lightest and has the second best battery life currently available. It is also night vision compatible on the lowest of the 8 brightness settings
On the SGL31
The original two in the States: 100006 and 100009
Miglan20 originally owned 100006, when he sold it the buyer was in Houston Texas (and a good friend of mine) so now both are in the same shooting club.
I am aware the -VS has been in military trials and as of 2014 may have been accepted for use on the AK103. There at least one is being used in the field.
