Thread: Jw15 modifications

Had a bit more of a play with this once the kids were in bed. Took a bit of work to get the trigger into the stock, once it was in the pull was lighter than the original and a lot smoother. There are a few reasons for this, first the sear engagement with the original trigger is set by the shape of the trigger stamping and sits against the bottom of the receiver, this was a bit tricky to meassure (and make accuratly) so I put the additional grub screw close to the pivot. This is further away from the pivot than the original contact point. This screw could be used to control sear engagement but Im not so keen on that as there isnt a lot of engagement to start with but it can be set so there is no slop in the trigger, when set like this with the second screw out it is a reasonably light single stage trigger. As the second screw is wound it it becomes 2 stage again with a slightly lighter pull than the original. The second screw is in the same position as the original one but is much bigger, I found the origninal one had been cutting a groove into the bottom of the recevier making it quite gritty. I filed then stonned the bottom of the recever to get rid of the groove, the brass screws should wear before the recever.
