Ya know, I'm familiar with the concept, but I kinda wonder if they are a little specialized for military applications.
I can't imagine any way to actually suppress a rifle without sending the gases all hither and yon. That's got to play holy hell with sniper level accuracy...especially with multiple shots.
Also, the payload to powder ratio has got to REALLY restrict the range those things are good at.
I'm sure they're great for sentry removal (how ironic), but general application?
The weapons are good to 300 meters in skilled hands,and modern suppressors don't hinder accuracy.The new suppressors work by cooling and redirecting the expelled gases internally with multiple baffles and ported tubes.Mine works great,but does heat up fairly quickly.
