EDIT: maybe too close for 14x1LH... Reference diameter for an AKM muzzle is .572". Might be cutting it real close.
In my experience the CNC Warrior muzzle devices are tapped on the tight side. If you buy a muzzle device from them it will likely not rattle.
Regardless if you want to use another 14x1 device, you can always remove some material from the rear face of the device where it butts up against the FSB. Work slowly to get a clean face surface and eventually you can time it up so that the detent pin engages as the device is fairly tight against the threads.
Of course you will need to get the detent spring and pin. This requires you knock out the forward FSB pin. Get a quality starter punch and punch set to do this, make sure to distribute the load evenly across the FSB side and not against the FSB ears - they can bend or break.
If you damage the FSB pin you can make another from 3mm drill bit or 3mm pin stock, available at most fastener stores - e.g. Fastenal or McMaster Carr
