712 324 7409, You will probably talk to Dean Van Marel. I am confident He can provide what You need.
I now have the safety bar installed, and My trigger has settled out to a 7oz pull weight. I cannot make it slam fire or bump fire. I have found it to be like the SSS trigger, and others, the sear engagement setting is perhaps more important to the pull weight than the trigger spring.
There is a “but”. The trigger has creep. I have not been able to get it out or reduce it. I will continue to work on it.
Good Luck :cool:
edit...I touched all the screws with blue locktite after final adjustment. Hopefully, this will keep everything as it is.
