Firearm suppressor booster system

A booster system for a firearm suppressor comprising:

• a piston housing including an annular outer wall and an annular projection extending radially inward from the outer wall at a rear end of the piston housing, the annular projection forming a front-facing shoulder;
• a piston disposed within the piston housing and including a bore for the passing of a projectile from a firearm and a radially outwardly extending flange at a front end thereof, the flange forming a rear-facing shoulder;
• a spring radially disposed in an annular space between the piston housing and the piston, the spring engaging the front-facing and rear-facing shoulders;
• a rear cap including:
• an end wall extending radially outward from a rear end of the piston housing, and
• an annular side wall extending forward from the end wall over the outer wall of the piston housing and at a radial distance from the outer wall of the piston housing, the sidewall including a first cap engagement surface;
• and
• an interface disposed around the piston housing and including:
• a second cap engagement surface disposed at a rear end of the interface and engaged with the first cap engagement surface of the rear cap, and
• a casing engagement surface configured to engage with an outer casing of the suppressor.
