Optika6 3-18×50 and 3-18×56 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 the 4C are 0.25 MOA.  Available in several reticle configurations including optional illumination and DichroTech, the 3-18×50 and 3-18×56 are designed with hunters and shooters in mind.
