- Low-back-pressure design reduces back pressure by 60% compared to conventional suppressor designs — less toxic gas in the shooter's face, improved reliability, superior recoil control, and a cleaner-running firearm.
- All-new muzzle design improves gas flow and significantly reduces flash, with flash suppression holding from the first round to subsequent rounds even when the suppressor is hot; the beefed-up muzzle also improves durability against front-end impacts.
- Measures 6.3 inches long and adds only 3.8 inches to the firearm; actual added length varies depending on which SureFire adapter is used.
- Next-generation SureFire gas flow dynamics further reduce flash signature
- Patented, tool-less Fast-Attach® design allows quick, easy attachment and removal
