Khan testing the 5.56 suppressor from "Jet Suppressors" using M855 SS109 with 10.5" barrelled SBRs.

Jet uses strictly titanium to build their suppressors for light weight and durability at high temps.

Not understanding the proper applications for suppressors combined with Hollywood movie hype has misled the general public to believe suppressors are only effective with subsonic ammunition. This is a common misconception.

The remaining noise which you can hear on this video of the suppressed shots cannot be fully appreciated by watching a video reproduction alone. In person, the difference is incredible.

Without the suppressor, firing an SBR 5.56 is extremely loud and can easily cause permanent hearing damage. With the suppressor attached, the noise is reduced to about the level of a loud handclap at the area of the gun.

Downrange is where the effects are really impressive. The sound of the bullet impacting a target is much louder than the gunshot itself, and with the explosive concussion absorbed by the supprressor, leaving only the sonic crack, whoever may be near the target may possibly hear the shot, but their ears will never be able to distinguish the direction of the shot from over 100yds or more especially in high wind.

By limiting suppressor use to subsonic ammo, the sound is reduced to less than a pellet rifle, but the effective range is dimished to less than 150 yds instead of the full 450 or beyond. Subsonic rounds are extremely limited in range.
