Thread: JW 15 - tips, tricks and modifications

The trigger is a two stage. The grub screw under the trigger only adjusts the length of dead pull on the first stage. It pivots on a pin to activate a sear bar. Very gently polishing the top of sear where it engages the bottom of the firing pin from inside bolt will affect break.
Dremmel polishing wheel with autosol. separate the bolt components. polish the flat underside of the firing pin.
@mudgripz can show us a lot of tips on these.
