- Free-float suppression unit expands inside the body, so the suppressor does not bend or twist when hot.
- The suppression module is user-swappable, which changes the caliber the suppressor is rated for.
- No minimum barrel length restrictions.
- Flow-through design vents combustion gases forward rather than trapping them, so no adjustable gas block or other rifle modification is needed.
- Full-auto rated with the stainless steel body.
- Controlled gas flow and rapid gas cooling eliminate virtually all flash, which prevents night-vision blooming on each shot.
- Fully serviceable: can be disassembled for cleaning and all parts can be replaced.
- Passes the SOCOM stress test cycles.
- Point of impact shift is 1-4 cm and straight down at 100 m in most cases; the taper-lock direct thread mount indexes at the same point on every remount.
- No harmful toxic gases directed to the shooter’s face and lungs, and no increased weapon fouling.
- Delivered with a storage pouch and a Front Cap Key (FCK) disassembly tool.
- The aluminum body is recommended only for 9.00 mm PCC carbines and single-shot rifles; full-auto rating applies to the stainless steel body with the flow suppression module.
