Im new to optics and got a Falcon menace 4.5-18-56 . It doesnt come with any instructions , just an allen key . I was wondering what it was for ? I ve zerod my rifle and was wondering if i could remove the cap so i can allign the zero to the 1st 0 notch ? Sorry for the bad explanation ...





























There is a male spline on the turret and a female spline inside the cap. There will be some resistance when taking off the cap because there is also an o-ring to seal it up. Take it off and zero it. Be careful when installing the cap to line up the splines or you may wreak it trying to push the cap back down.
