The PK-01VS is a newest, mil-spec, light scope simple in design and construction made especially to use with NV goggles. It is particularly reliable and sturdy. It is designed for accurate firing by hunting rifles in daylight and dusk conditions and is guaranteed to significantly increase your accuracy. It has an universal mount so it can be attached to virtually any weapon. It has a traditional bright 1 MOA red dot. The PK-01VS has a special 8 setting (first three positions are to use with NV equipment), discreet built-in variable brightness control allowing you to regulate the brightness of the dot manually. There is a special position of the switch - K - to control the battery condition. When you put the switch to this position and the dot is not seen, you should change the battery. It is overbuilt to handle the strongest of recoils and can be attached to any weapon regardless of caliber. The sight is waterproof and dry nitrogen purged to prevent fogging. It works well with night vision optics. The open windage and elevation knobs are easily accessible for adjustment and have clear, pronounced .5 MOA (1.5 cm at 100 m) clicks. Russian sights are particularly popular for having open uncovered knobs that are finger adjustable. It comes with a full set of accessories including lens caps, tool, sun hood, fire card and a soft carrying case.
