MGS-Mod 1 Suppressor


  • Increase reliability and longevity with host firearms due to low gas blowback and low gain in host weapon cyclic rate. (4% cyclic increase on FN M240 Lima).
  • Drops sound to well below hearing safe levels (specific reduction based on caliber, weapon configuration, and atmospheric conditions) average measurement per MILSTD-1474D of 136dB.
  • Decreases flash, decreases recoil, and increases accuracy.
  • Fully and easily serviceable.
  • Disassembles with common tools.


  • The Maxim Defense MGS-Mod 1 Suppressor is specifically designed to minimize the increase in cyclic rate and gas blowback of a suppressed weapon system.  Primary design features include a significant reduction of sound signature, decreasing flash signature, reduction of recoil, and increase in accuracy.
  • During installation, the suppressor locks into place with a specific torque on the core then is pinned onto the barrel for absolute assurance of installation. When installed to spec, this method ensures the suppressor will not loosen during fire.


  • State-of-the-art MonoKore design.
  • Self-torquing during fire
  • Military-grade materials.
  • Adds 10” to the muzzle.
  • Simple 2-piece design.
  • Designed explicitly for 7.62x51mm MMGs.
