I bought a cut caryng handle w/o the detent on the elevation drum.  The seller included the ball bearing to make the drum click when adjusted.  I went to instal it and every thing went fine except I need to find the spring that would go under the bearing that goes under the elevation drum.

What would you call that little spring

I assume once I find the name of the thing BM, RRA etc would sell such a thing.


Thanks in advance,
Joe

It is called the Rear Sight Helical Spring and Bushmaster has them listed here.

Thank you Thank you!
