The PK-01V Military Red Dot w/ Brightness Adjustment is a modern, mil-spec, light scope simple in design and construction. 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 a standard 30 mm tube so it can be attached to virtually any weapon. It has a traditional bright red dot with a minimum MOA of 1.5. The PK-01VA has a special 8 setting, discreet built-in variable brightness control allowing you to regulate the brightness of the dot manually. 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 2/3 MOA clicks.
