Grunt-M (mini)

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.
