GRUNT-M 5.56
At only 5” and 13.5oz, the Grunt-M (mini) is the most compact, quiet, and lightweight in its class. It is the micro version of our Grunt® 6.25″ performance silencer. It is designed specifically for security forces doing entries to stay compact and still has an impressive sound and flash reduction to stay in constant contact. With our patented one-piece core, the Grunt-M is manufactured from billet bar stock without any internal welds, ensuring that you get the best possible performance and durability. The Grunt-M is full auto rated and can be easily installed on barrels with a 1/2 x 28 thread, even on those as short as 10 inches. Its wrench flats make it easy to pin and weld on short barrels. You can choose from different colors, including Black, OD Green, FDE, Burnt Bronze, or Brushed Stainless, to match your preference. With a .22-250 rating and our patented Exoskeleton Shroud, the Grunt is a perfect fit for your 5.56 rifle, whether you’re on the range or on the job.

Write Your Review Works perfectly with my 11.5 inch Upper and SBR Lower receiver set. Using adjustable gas help's with the blow back of the gas and grit. It's difficult to suppress a non subsonic round's, However with my home brew loads I'm able to eliminate virtually any sound at all. Down side is the rifle will not cycle with these subsonic rounds and becomes a single shot. That said the Grunt suppressor is extremely good at reducing the heavy crack of a 5.56 round going off and makes shooting a lot nicer. I purchased the grunt mini in 2009 and I’ve put thousands of rounds through it. The finish looks worn now but the suppressor is still as quiet as the day I brought it home. It is such a small suppressor that I don’t notice any weight difference on the rifle. The grunt mini is used mainly on my 16″ AR, but we also have put it on the 1022 and it actually sounds really good. I own two other IA suppressors (Sligshot, LDSP) and a few from other companies. I have been beyond pleased with my IA suppressors and have had zero issues.Grunt-M (mini)Average rating: 2 reviewsSandstormDec 26, 2017
