Ball detent length???

[purplemag]

I am installing a second ball detent into my ptp Micro E-mag. How far into the breach should the ball go? End of detent threads flush with breach?
Keep in mind I will still have my ptp detent installed.

set the bolt in the cahber and dont overtighten make sure the bolt freely moves back and forth without bunping or rubbing the detent you can use spare o-rings from lvlX kit to add more space between detent
