How well does the Galil ACE suppress?

Friend of the blog Joe filmed and put out this comparison between the (gas) suppression of an IWI Galil Ace and an LMT MRP AR15 (more info on each gun below). Interesting results. Make sure to give Joes channel a follow.

From the video description:
IWI Galil Ace Gen 1 5.56 (8.3in)
-KNS adjustable piston
-Rex MG7 .224 suppressor

LMT MRP 5.56 (10.5in)
-Carbine length gas
-Dead Air Nomad 30
