SUBSONIC 223 DECIBELS FULL

I have experimented for years with center fire subsonic rifle calibers and we always had to shim the scope ring base to keep target in field of scope view, which isn't really practical. Some on other talk forums have claimed they can engage targets beyond 300yds, which has never been proven with video footage or actually witnesses. The law of gravity factors in every time. Now for the meat of the subject is, what does one really again with heavy rifle projectiles traveling at 1050fps? The answer is nothing much over 100yds, because the projectile drops like a rock after 118yds. Most suppressed AR15/M16 owners are turning to the 300 Fireball, 300 Blackout, or 300 Whisper AR upper systems for lower cost of ammo, but these systems will only accommodate 30 caliber rifle suppressors. 1050fps is targeted projectile fps in general. From 1080fps to 1120fps will increase port signature before actually breaking the sound barrier. To limit supersonic port signature requires projectile speeds below 1100fps infringing threshold of the supersonic sound barrier. 223 / 5.56 is one of the most difficult calibers to suppress because of small weight projectile moving at super fast fps rates.

223 / 5.56 subsonic manufacture that offers full cycle rate of semi-auto and full-auto fire. Sierra Match projectile.Įxtreme Shock is the only current. The ammunition intentionally does not cycle the action, for the ultimate in quiet shooting. It does not use fillers which tend to clog suppressors. Tumbles within 2-3' on soft tissue, producing a large wound channel. Other attributes: it is more accurate than M855 ammunition at 50 meters. (reference: Paulson 1997 Silencer Trials, Report BR-71). 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. ASP will fire in both semi and full auto mode, is not temperature sensitive, and requires no modification to the host weapon. The ASP needs a suppressor attached to make it function in full and semi auto mode. ASP is designed for the Colt M4/M16 family of weapons, but can be adapted to other weapons systems. The Advanced Subsonic Product (ASP) was developed to meet the needs of today's covert special operations teams, giving them astonishing stealth capability. This round provides maximum stealth, is lead free, frangible, and environmentally safe. When utilizing the 5.56 Covert round with a suppressed M4/M16, the only sound produced is, the hammer striking the firing pin, and projectile impact. Two of the best manufactures of subsonic.
