Manufacturer claim
- Sound reduction is rated at 32-35 dB.
- Engineered with a patented one-piece core machined from solid billet bar stock, the Grunt is devoid of internal welds, eliminating the possibility of weld failure.
- It has wrench flats for easy pinning and welding on shorter barrels, and is offered with an optional Exoskeleton Shroud that works as a heat sink.
- The Grunt boasts a full auto rating and is built to endure the harshest conditions and heavy use.
