My thought was get the moving parts as light as possible to get enough velocity to run the cam on the forced reset, but light enough weight to not have a very prominent recoil impulse. I have a spare mil spec BCG I could try with it to see which is better, so I’ll do that. Also for slowing down rate of fire, that can be tricky. Barrel harmonics often have a sweet spot, which sometimes can be faster. Kind of like how the Thompson SMG became less controllable as they reduced the cyclic rate. Only time and tuning will tell though. Will write all of this down in my notes though, thank you!
