1.5mm Allen Key for SRS Trigger

Long 1.5mm ball end allen key for adjusting the preload on the trigger/sear.

One of the most common issues for tough bolt pulls is a misconfigured trigger and sear, meaning there is a hard "clunk" at the end of the pull.

 By adjusting the preload you can remove the majority of this resistance.
