The SpecterOS4x Optical Sight is an optically brilliant instrument for precision aiming of service rifles and carbines. With superior low light performance and extremely long eye relief, the SpecterOS4x outperforms competing 4x optical sights and, as a result, has been selected for general service by advanced military forces.

Depending upon the situation, the user may light the central part of the reticle with brilliant LED illumination for CQB applications, or select lower-level illumination of the entire reticle for low-light operations. The SpecterOS4x Optical Sight comes in two reticle options: Dual illuminated ballistic crosshair and Dual illuminated ballistic chevron. Because the reticle is etched in glass, it is plainly visible even in the case of loss of electrical power due to battery failure or EMP. The SpecterOS4x is an extremely rugged tool designed to withstand the rigors of modern professional use.
