Bear Mag T/D, what’s this for?

[Amberjack]

Howdy folks.

Dumb question of the day.

I feel like I should know this, since I've owned one of these before, but I can't seem to recall.

What's this screw for?

That's the mounting hole for the old single arm, spring arm quiver
The spring arm went on the upper limb.Lower part where the arrow gripper is had a metal tab with a notch in it that straddled the screw and was then tightend down

Great, thank you sir!
