Completed the build up of the semi Vltor PKM receiver assembly. This thing is a beast of a stamped receiver. Used some Plinker's riveting tools that I modified and fab'd up a couple new riveting bars to fill in where Plinker could not go on the PKM. Rivets/receiver countersunk on the rear trunnion and barrel trunnion. Still need to make or buy the semi parts (modify bolt, bolt carrier and the FCG) to make this thing go boom. Here's a few photos.
Sorry Pirate, didn't drag out the tripod this time
- edited photos to better show receiver rivets
