5.56mm NATO/.223 Ultra Stealth Match Subsonic

This is the most quiet and accurate 5.56 x 45mm "sub-sonic" round on the market, with a mil spec MIL-STD-1474D reading of 117dB when used in conjunction with the Gemtech M4-QD suppressor and an M4 Carbine, and 114 db with the SRT Hurricane on an identical weapon. (reference: Paulson 1997 Silencer Trials, Report BR-71). Other attributes: it is more accurate than M855 ammunition at 50 meters. Tumbles within 2-3" on soft tissue, producing a large wound channel. It does not use fillers which tend to clog suppressors. The ammunition intentionally does not cycle the action, for the ultimate in quiet shooting. 63-gr. Sierra Match projectile.
