Finally had a chance to test the buffer weight today, there is still a bit of bolt bounce. Lead shot is proven to be not enough, I have tungsten rod on the way . Should be able to significantly increase the amount of weight inside the buffer. Current setup adds about 11g only, container is about 7g, the lead shot( moving weight is only about 4g)

Also testing the durability of the printed parts in the trigger, will take it apart to see how it’s holding up.
