Manufactured in Finland by Ase Utra OY, the jet-Z™ COMPACT-BL suppressors incorporate Ase Utra's patented jet-Z™ baffle system.

jet-Z™ COMPACT-BL suppressors are all-steel, all-welded units rated for professional use on semiautomatic and select fire weapons.

The tapered surface on the BoreLock flash hider blocks almost all of the fouling from going into the attachment thread area, enabling easy removal of the suppressor even after several hundred rounds.


jet-Z™ COMPACT-BL suppressors reduce the sound pressure level of a an assault rifle by c. 15-28 dB, depending on weapon type and measurement location.

In addition to the reduction in sound signature, the suppressor also reduces recoil and an added benefit is the elimination of visible muzzle flash, especially for military users.

* Suppressors can be used on these calibres, however the bullet channel is oversized compared to the calibre, possibly affecting suppressor performance. Also the suppressor may be too short, when compared to the power of the calibre.
** Safe to shoot, however the difference between the suppressor bullet channel and
calibre is quite excessive and clearly affecting the suppressor performance.
