Great question! Never a good answer. MY opinion only, Id look at the silencerCo omega, thunderbeast ultra 7 or 5. I have a AAC cyclone I use on the grendel and a blkout but its heavy. Iv heard my buddys omega on his blkout and grendel and its awesome. My ultra 7 is STILL in jail but I cant wait to hear in on the grendel. I wouldn't mind trying the TBAC ultra 5 out also. Just my opinion but I think the Omega will be hard to beat for the money for what you get.
