SilentStrikeTM is the worlds only full functioning 223 subsonic round that will operate the AR and M4 weapon platform at 975 FPS in semi and full auto.
SilentStrikeTM uses a dense compressed powder metal core to achieve bullet densities that allow the round to generate sufficient gas pressure to operate the gun.
SilentStrikeTM can be engineered to act as a solid if penetration is needed or as a frangible if fragmentation is needed for greater tissue damage. A 1x7 twist is required for best results. It will work at a limited range in a 1x9 but will not be as accurate at the longer ranges. No modifications to the host weapon is needed. SilentStrike is based upon a stock factory spec which is a H buffer, stock recoil spring and a min .065-.070 gas port.
SilentStrikeTM delivers whether the user is a varmint hunter, law enforcement personnel, or part of a covert team needing astonishing stealth combined with maximum power and performance.
