At only 5” and 13.5oz, the Grunt-M (mini) is the most compact and lightweight in its class. The patented one piece core is machined from billet bar stock and has no internal welds. The GRUNT-M is direct-thread on in 1/2 x 28 and is full auto rated on rifle barrels down to 10″. It also features wrench flats that allow easy pin and weld for short barrels, and is available in Black, OD Green, Flat Dark Earth, Burnt Bronze, or Brushed Stainless. The Grunt- M is rated for .22-250.
*The GRUNT-M is also available with our patented Exoskeleton™ Shroud. * The Exoskeleton™ Shroud gives many advantages, it also works as a heat sink and gives added grip when mounting the suppressor to the rifle.
As with all our silencers, the GRUNT-M can be fired “wet” or “dry”.
Do not use a crush washer in conjunction with any Innovative Arms silencer.
