quick question regarding the thread pattern on the end of the barrel on the FCP-K......Is there an "industry standard" so to speak in regards to the thread pattern used on muzzle brakes and/or silencers? I was just curious if I could get lucky enough to be able to acquire this http://www.advanced-armament.com/pro...id=209#pid=211 and be able to switch back and forth between the two? I am not familiar with industry standards (if there is one) for thread patterns used on muzzle brakes and/or silencers. Or if the heavy fluted barrel is too thick to accept this particular silencer? Thanks for the help guys!
