OKP7 Green Dot Sight for Picatinny RaiI. The original design of OKP7 sights allows firing from unstable positions in rapidly changing conditions, reduces the operator fatigue, and, if necessary, allows unhindered use of base mechanical sights. The key feature of this sight is a rimless reflector attachment that doesn’t block any field of fire sections; instead, reflector is protected by thin and durable visor that is almost un-noticeable when firing. Classic Russian-style green color reticle. The OKP-7 is a precision-engineered green dot reflex sight that allows for quick, accurate aiming at close to medium distance for rifles with Picatinny rails. Side Lens Hood (Curved Cover See Picture): This curved hood protects the interior reflector assembly from scrapes and light impacts. It also blocks strong ambient light from the side and improves dot contrast. Lightweight Design: Reduces overall weight and improves maneuverability and mobility.
