PKM Build

 

Mock-Up and close-up pics of components.  These were made for reference so that I could obtain the measurements for my build. 

       

 

Conceptualization

Based on the Swiss STG design, a striker plate could be used with a side-mounted hammer. 

    

Another completely different concept is the use of dual springs to allow clearance for a semi-auto hammer.

    

 

Components

 

Auto sear lug - this must and will be removed before I build to ensure I meet the legal requirements.

   

Carrier.  Note the chafe marks.  Presumably these are from the rail and the ejection port rivets

                   

               

This hole appears to be part of the original mill work, perhaps an alignment hole for lathe work?  This is the part of the carrier I intend to use for a bolt-on striker system.

Trigger assembly and original components.  The housing is permanently riveted to the receiver.
