My goal is to try and bring down the muzzle velocity to ~400. I'm thinking about installing the low power bolt but I feel like that may bring the velocity down to only 410~440. So I'm thinking, what if I installed the flute valve inside the low power bolt? I'm not sure whether or not the low power bolt already has a flute valve design pre-installed, so it would be appreciated if someone could look into that.
Please let me know if anyone has tried any of these set-ups. thanks.
