DESCRIPTION The ACS E1 was developed to combine an excellent balance between weight, size and durability with outstanding noise and flash reduction. Machined from bar stock and CNC laser welded, the ACS family of suppressors shines even under the harshest conditions. All ACS E1 feature Acheron’s proven HexaLug quick attach mounting system, revolutionizing suppressor installation. Finished in Cerakote’s C-Series high-temp coating, the ACS E1 is available in black and Flat Dark Earth. Sound reduction represents the difference between the logarithmic averages of two 5 round groups (unsuppressed / suppressed).
