Optika6 3-18x50 and 3-18x56 riflescopes are available with First or Second Focal Plane (FFP / SFP) reticles. SFP models have capped windage and elevation, while FFP models have exposed locking elevation and capped windage. FFP models also feature a zero stop elevation turret that allows the shooter to have a definite return-to-zero point no matter what distance they have dialed in for. Standard click values for non-MIL reticles are 0.25 MOA, while MIL based reticles feature 0.1 Milradian per click adjustments. Available in several reticle configurations including optional illumination and DichroTech, the 3-18x50 and 3-18x56 are designed with hunters and shooters in mind.
