I have a M4-2K I bought in 07, I'm currently using the 18-Tooth A2 mount it came with.  I need some more muzzle brakes for different builds, can I use a 51-T muzzle brake?  Any problems?

Only the 18 tooth mounts will work.

Thanks...Any idea where I could find some?

On the EE would be my opinion.
