The ACS E1 was developed to offer an excellent combination of weight, size, and durability with top-notch noise and flash reduction. Made from a single piece and CNC laser welded, the ACS suppressor family shines even in the toughest conditions. All ACS E1 suppressors can be mounted using the HexaLug quick-attach system.

The surface finish is Cerakote's C-Series, resistant to high temperatures. The ACS E1 is available in black and brown (FDE).

Noise reduction is measured as the average between two groups of five shots (without suppressor / with suppressor). Ammunition: RUAG GP90 Weapon: AR-15 (Geissele URG-I 14.5″) Muzzle device: Acheron HexaLug flash hider
