FPM Gunworks M-80 Features The FPM Gunworks M-80 is machined from 17-4 stainless steel on precision CNC equipment giving the brake tight tolerances for consistent suppressor mounting and reliable muzzle brake performance on 30 / 7.62mm rifles. Its design allows it to fit directly onto the Q Plan B mount as well as the Rearden Atlas and Atlas XL mounts giving shooters flexibility in how they configure their quick-attach suppressor system. Threaded 5/8x24 the M-80 installs onto standard .30 caliber barrels without requiring a gunsmith. The Black DLC finish adds a hard wear-resistant coating that protects the brake from the heat and fouling generated by sustained firing. At just 1.750 in overall length and 1.70 oz the M-80 adds minimal length or weight to the end of a barrel keeping the rifle s balance close to its unmodified configuration. The brake functions effectively as a standalone muzzle device for reducing recoil and muzzle rise or as the mounting interface for a suppressor when paired with a compatible quick-attach system. Its compact dimensions make it a practical choice for precision rifles and hunting rigs where added length at the muzzle is undesirable. The FPM Gunworks M-80 gives .30 caliber and 7.62mm shooters a versatile well-machined muzzle device for recoil control or suppressor mounting.
