    Default Trigger pack conversion question-help

    I'm converting the G3 trigger pack to semi-auto. I have already installed the "shelf" at .400" and the trigger stop pin in the proper places. What I'm not sure of is the "new" hole for the sear AR-15 spring and pin. I have the drawing I found on the Web, but the dimensions are a little vague. Can you tell me/ photos / dimensions as to where the new hole needs to be to support the sear spring. Also, is there a good,clear, drawing or series of photo's that show all of the trigger group semi-auto parts going in place or and exploded view diagram of these parts. Thanks guys for your help.

    Wish I had known about that site this last weekend. The trigger spring came off the little shelf and I had a devil of a time figuring out the disassembly and reassembly of that mechanism.

    I printed it to keep in a binder with all the HK maintanance/troubleshooting info I run across.

    I use a #10 jobbers drill bit for the sear spring hole.

    Thanks for all of the answers. I still don't know just where to drill the new sear/spring pivot hole.

    Rapidrob. How did you determine the correct location for the trigger limiter pin? Does a drawing exist on-line with measurements to help locate the hole? Thanks. Chris.

    In all the years I've been building CETME C's with G3 fcg this is the best drawing I've seen. Most of the time the build tutorials don't carefully explain the sear spring modifications. BTW people have also used AR15 hammer spring. I have also used a light spring from old CETME fcg. However it is too narrow so not a good solution but it works. As best I can tell the roller on original spring is only needed for the thin original thin spring. As long as sear spring can slide smoothly on the sear I've had no problems.

    Link to Weapons Guild discussion on using the AR15 hammer spring is here.
