Allegiance Ammunition SilentStrike – Subsonic .223
Allegiance Ammunition has an interesting product, their SilentStrike .223. SilentStrike purports to be the worlds first fully functional sub-sonic .223 round. The bullet is 100 grains and in the video, Allegiance claims it will work in the AR-15, M4, and HK-416. Down a 16″ barrel, the round is reported to be at 975 fps velocity. This equates to about 200 ft/lbs, or about half of what 9mm typically provides in 4″ barrels.
