The main problem is that they can be dirty. Very dirty.
DUDE, new info that rocks.....Thank you. So now it's obviously time for me to research some updated subject material.
The last thing I was up to date on* was a small company changing some AR internals to a "silent" roller bearing system, changing or tweaking something in the gas return system, and using 5.56 sub sonic ammo. The result was something that sound like a crossman BB gun, but had lethal stopping power out to 300 yards.
*Some time just before Surefire started to manufacture silencers.
