he new Ase Utra ECOi rimfire suppressor provides improved sound suppression and is intended for both pistol and rifle use. .17HMR spesific version of ECOi is also available.

The suppressor allows the use of iron sights or low mounted optical sights. The standard threads for the suppressor are 1/2″ x 20 UNF or 1/2″x28 UNEF.

The suppressor reduces the sound pressure level by ca. 29–33 dB on a rifle and ca. 28-31 dB on a pistol. It should also be noted that the first shot with the Ase Utra suppressor is as quiet as the following ones, so there is no significant “first round pop”.
