The Universal Ultra Low Concussion (US15) System design allows for installation over most any standard muzzle brake (maximum muzzle brake size: 1.25" OD). The US15 System takes advantage of the state of the art Computational Fluid Dynamics software currently available. Designing for specific dynamic goals, the US15 System allows superior reductions in firing point concussion and overpressure! Designed for CQB and Ultra Low Concussion to operators (223 & 308 AR style systems). Also designed for long range tactical rifles. The US15 System does not reduce sound like suppressors do. It reduces felt concussion (overpressure) from the shooter's position as well as those nearby.
The US15 System is available in a Standard System configuration with a removable shroud, & lock nut.
The US15 System is also available in a Professional System configuration that includes the Standard System plus a Vented shroud for second stage recoil reduction and low concussion.
