RE: AR34 ram 1/2?
Try 1/16 nock high to start.
nock an arrow....hold teh TT up with the arrow on it and look down teh back of the bow. Line your eye up so that teh string completely bisects the riser taps in all 3 places on the back....now glance at the arrow. If the arrow is not also bisected by the string adjust it so it is.
That will get ya shootin'...provided you have the proper spined and matched arrows.
I have 2 AR34 ram.5s. One camo and one blade for indoor and 3D. I love them.
