- The 5.56 Ultra Stealth Match Subsonic is the most quiet and accurate 5.56 x 45mm NATO Subsonic round on the market. Testing backs up this claim, with a mil spec MIL-STD-1474D reading of 117dB when used in conjunction with the Gemtech M4-QD suppressor and an M4 Carbine. A reading of 114 db was obtained with the SRT Hurricane on an identical weapon. (reference: Paulson 1997 Silencer Trials, Report BR-71). Our 5.56 Ultra Stealth Match Subsonic is more accurate than M855 ammunition at 50 meters. The projectile tumbles within 2-3" on soft tissue, producing a large wound channel and making it an ideal small game hunting round. We do not use ﬁllers which tend to clog suppressors. Also, this ammunition intentionally does not cycle the action, for the ultimate in quiet shooting. Please closely follow all recommendations when using this ammuniiton.
