Hueco,
After I purchased my Bushmaster the first thing I ordered was a set of Pro-ears "Pro-Mag" model. I only have one ear that works, I take no chances. The .223 is LOUD. I almost bought the Shorty AK, but many people told me that the AK brake would deflect noise back at me. I chose the plain barrel Shorty. I'm really happy with it. I have some .22's, they sound like pop-guns compared with the AR.
As far as recoil, well it's light.
Will
