"Critical Mass is something of a novelty company. The guns function very well but a little gimmicky for real soldiers to use. Critical Mass is most famous for its "Sublight COM2" rifle round that uses technology similar to air burst munitions to trigger an ultra high speed event in the final meter before target impact through "Centre of Mass Displacement" technology."
