Lost my beiter plunger springball


New member
Trying to get back into archery so started shooting my target recurve bow 2 weeks ago. I noticed that my Beiter plunger's springball seemed to have fallen off and it now doesnt click.
I know Beiter selles parts, but they are not available locally (Philippines). My question is, can this piece be bought in a hardware or screw store, and if so, what size is needed?
