Zackery, This muzzle device is not suppressor compatible. You can remove the existing Sig Gen II muzzle climb mitigation device and put a quick attach muzzle device on for suppressor you have. Or you can just direct thread the suppressor to the barrel when you remove existing proprietary muzzle device. NOT Suppressor ready out of box unless you have a device that will fit with the existing muzzle device.

yes it is just remove the muzzle brake and screw on the suppressor

Zachery, yes Sir. This 18" chrome lined phosphate finished CMV barrel has Muzzle threads of 1/2x28" and will accept the same thread pattern AR Silencor's without issue.

Hi Zackery, All you need to do is remove the muzzle brake and screw on the suppressor
