SilentStrike 556 130GR 1050 FPS is the worlds heaviest 556 Jacketed Frangible Full Cycling subsonic round that will operate the AR weapon platform at 1050 FPS in semi and full auto and that is safe to shoot in suppressors.
Using a dense compressed Tungsten powder metal core we achieve core densities that allows the round to generate sufficient gas pressure to operate the weapon at 1050 FPS. The dense tungsten core allows SilentStrike to penetrate through thick bone and hide to reach the vitals. Even at the lower velocity depending upon the caliber and shot placement SilentStrike has a certain amount of frangibility in soft tissue that helps create a larger wound cavity to stop the threat sooner. Because SilentStrike is a powder metal core it will fragment on surfaces that would cause lead bullets to ricochet making it ideal for around sensitive areas and metal enclosures.
SilentStrike is designed for a 1×7 twist, NATO chamber with a min gas port of .075 in a 16″ barrel, standard weight buffer, Sprinco White spring. The biggest majority of ARs built is built with that spec or very close to it. If your gun won’t function with SilentStrike it has an extremely good chance that a simple change out of the buffer, buffer spring would be all it takes to make it run. Other problems that can show up will be the gas port being to small or the gas port and the gas block being misaligned. Small problems like that will not show up with standard 556 ammo because of the mass amount of gas pressure that the ammo generates and the gun has to work with. But all of those are easy fixes. SilentStrike is a very specialized round for a specialized application so the gun must be built to a Quality spec and kept in good operating condition. We have seen guns that when brought to us that would not function with SilentStrike that after a good thorough cleaning it worked just fine. We have SilentStrike working in our 16″ platform all the way down to our 7″ upper and it works in semi and full auto mode. So it can function and be loaded in shorter SBRs if the gun is set up correctly. So FULL CYCLING 556 SUBSONIC AMMO can be 100% FUNCTIONAL if you set the gun up right. No special modifications or adjustable gas blocks are needed. If you are having problems please give us a call and more than likely we can solve the problem over the phone.
SilentStrike delivers Silent and lethal performance, whether the user is a varmint hunter or LE personnel in an Urban CQB environment where stealth and Quiet lethal performance is needed to ensure a successful mission.

SilentStrike is produced under strict specifications with strict quality control and is designed to fit a NATO spec chamber. If your bolt does not fully lock up that means you have a 223 Rem or Wylide chamber and IT WILL NOT WORK in a 223 Rem or Wylide chamber. Because you have an AR15 does not mean you have a NATO chamber.
