FPM Gunworks M-80 Features The FPM Gunworks Silencers M-80 is machined from 17-4 stainless steel on precision CNC equipment to deliver a durable tight-tolerance muzzle device for 5.56/.223 rifles. Its 1.75 inch overall length and 1.7 ounce weight keep it compact and light adding minimal length or bulk to the end of a carbine barrel. The Black DLC finish adds wear resistance and a low-visibility appearance that holds up to heat cycling and repeated use at the range. Threaded 1/2x28 the M-80 installs on any standard threaded 5.56/.223 muzzle without requiring a specialty tool. What sets the M-80 apart is its dual purpose design engineered specifically to fit the Q Plan B mount and the Rearden Atlas and Atlas XL mounts so it doubles as both a stand alone muzzle brake and the mounting interface for a compatible suppressor. Run alone the M-80 helps manage recoil impulse and muzzle rise for faster follow-up shots. Attach a suppressor equipped with a matching mount and the same part becomes the quick-attach interface saving the cost and hassle of swapping muzzle devices. For AR-15 builders who want one part that functions as a brake today and a suppressor mount tomorrow the FPM Gunworks M-80 is a practical addition for sale at GrabAGun.
