I finally am getting around to sighting in my Kobra sight  EKII-1C-03  that I have had for a while & discovered that  couldn't turn the adjustment wheel....The windage wheel worked fine... Upon further examination, I discovered that the ball detente & spring had 'gone Elvis' ..... Hopefully this is the only problem as turnng the spindle under to wheel seems to have no effect on moving the dot up or down.......E-mailed Tantal but haven't gotten a response thus far......Is there a good source for Kobra parts or will I be forced to 'ghetto rig'??.......Suggestions??.....

Tantal will help, hes a busy guy, give him time to respond.  Im not sure Im familliar with the term gone elvis, so if you could detail your problem then i might be able to help.  The kobras are a bit of a bitch to adjust past the stops so zeroing can often be tricky if you havnt fuddled with the dials for a bit.  But once you get it on........watch out, that things gonna suprise u.  Also, i have found that if you zero the Kobra to 50 yards, because of the hight of the optic and the trajectory of the round, you will have a near zero at 50 yards and a far zero at 150 yards,  all you need to do to shoot dead on at 100 is to rotate the elevation dial clockwise to 1.  To be dead on at 200 rotate the dial two clicks counterclockwise from zero, 300-3 clicks counterclockwise from zero, 400- 4 clicks counterclockwise from zero.

This actually works!

heres the data to back it up:
