What buffer and spring did you end up running with ss or arc fire? Any info appreciated.

I kept removing material on the front bottom of the cam disconnector a little at a time and its function testing perfectly. (B kings 3 round burst kit) with arc fire first gen. I am confident it will perform perfectly. The strike trigger tester is an invaluable tool to test your setup. Thanks to all that contributed to this project.

I have 556/223, 308 win and a 6.8 spc II.

Cheapest tungsten buffer weights? Even on Amazon they are 60-65 bucks for a 3 pack.

I have never dealt with them but they are offering the arc fire ambi (v1) at 50% off.

After using the advice of tacticalgarand44 (much appreciated), I purchased an extended tip firing pin from black rifle arms and as of today I have 300 rounds on the rifle using win m855 ammo with 0 malfunctions. Black rifle arms markets the extended tip firing pin for 7.62x39 ammo with hard primers. They even have an extended tip plus that is even longer. Anyway, just the extended tip solved all my issues. Hope this info benefits the community. Have a great day.
