Like new Rugged M249 SAW suppressor mount. 9/16x24 left hand thread and indexes off the muzzle. This is specifically for the M249 Para barrel but any 9/16 left threaded barrel. Fits all Rugged centerfire suppressors/silencers, I think this fits the FAL too. Worked very well, I just ended up changing the barrel set up, has less than 60 rounds through it. $75 shipped
