I was readying for a caribou/sheep hunt last night and noticed 2 round head /allen screws, 90 degrees of the limb mounting bolts. They were loose so I tightened them. They don't go thru the riser, just on the left side (left handed bow). There is nothing in the manual on them. Anyone know what there for? Thinking - for securing the limbs once adjusted.

Thanks, Dave

My pro 40 has them also and you are correct, they are set screws.

Thanks! It is kind of funny. Have had the bow for three years but am usually too busy looking through the sights to have noticed them.
