Indexing Your Booster

So you just got your new Cosmic (or Mystic X or Centurion) and you’re pumped. Trust us, we know the feeling! You head to the nearest range to try this bad boy out, but something is off. You know your pistol is dead on at 15 yards, but when you screw on your new can, you’re shooting low and right about 1″, pretty consistently. What’s the deal?

Point of impact (POI) shift is a standard phenomena that occurs when shooting with a suppressor. The baffles inside a suppressor are designed, essentially, to cause turbulence in the gasses leaving the barrel of the firearm when a round is fired. This turbulence is what causes the gasses to slow down and cool slightly before leaving the end of the suppressor, thus reducing the sound of the muzzle blast. Some of these turbulent gasses can push the bullet slightly, causing a POI shift. Barring anything out of the ordinary, like a baffle strike or unstable round, this POI shift should be consistent and repeatable.

A great trick with the booster assembly, is the ability to index the suppressor, or rotate it while mounted, to be able to adjust the POI slightly. This can be done by simply utilizing the way the booster assembly and how it is actually made. First, visually and physically verify the firearm is cleared of any ammunition and the safety is on. Second, make sure the suppressor is not hot to the touch. Grasp the firearm with your dominant hand, remembering rule four of firearm safety by keeping your finger out of the trigger guard. {Fig. 1}Fig 1 Grasp the suppressor firmly with your support hand and pull it out, in a straight line, away from the firearm, compressing the booster assembly spring. {Fig. 2} You can then rotate the suppressor and allow the piston to drop back into any of the 10 slots in the housing.Fig 2

For example, if you find that with your suppressor, you are shooting low and right (4 o’clock), most shooters will index the suppressor counter clockwise 3-4 positions to move the POI to directly above center (12 o’clock). This allows the shooter to know exactly where to aim when shooting targets.
