Instructions (1) Focusing • Look through the eyepiece with your eye positioned about 10cm (4 in) away from the eyepiece lens (Fig. 3-1), and you will see the Nikoplex reticle (Fig. 3-2), or the BDC reticle (Fig. 3-3). • Be sure your eye is positioned within proper alignment and proper eye relief otherwise the view will "black out." • Point the objective end of the scope at the sky (Do not point at the sun) or at a plain unpatterned wall. • Loosen the lock ring. • Turn the eyepiece adjustment counter-clockwise and then turn it clockwise until the reticle appears sharp. • Finally, without moving the eyepiece adjustment, turn the eyepiece lock ring as Fig. 3-4 to end so that the eyepiece adjustment will be firmly locked. The lock ring must be firmly tightened to ensure an air-tight seal. (2) Magnification • The riflescope 4x32 has a fixed magnification of 4X.
