Beautiful! You made/machined that Chassis yourself? Very cool! What material is it made from? Can’t tell for certain.

So it sounds like your striker spring was weak? And with the new striker & spring there were no light primer strikes, or NO primer strikes, correct? Only, I’m having trouble understanding your meaning about the trigger hitting the spring & such. And then, do you mean you took the non-Accutrigger out of the 223 to use in 6mmGT rig? Just can’t visualize what parts are contacting one another & causing a problem. But if you got it to function correctly, there the important part. Again… Great looking rig.
