The Ase Utra DUAL rimfire suppressor features excellent sound suppression and is intended for both pistol and rifle use.

The suppressor is manufactured from steel components and therefore has a very long service life.

The robust construction of the DUAL rimfire suppressors allows for use on a number of calibres, in addition to the .22 LR calibre, the suppressor can be used on .22 WMR and .17 HMR.

The finish on the suppressor is manganese phosphate.

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 can be taken apart for cleaning and maintenance.


The suppressor reduces the sound pressure level by c.28-32 dB on a rifle and c. 35-40 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”.

The reduced sound pressure level removes the shooters risk of receiving hearing damage and also reduces the environmental noise significantly.

The Ase Utra rimfire suppressors comply with the latest personal exposure limit set by the European Directive 2003/10/EC (140 Pa or 137 dB (C))
