The Ase Utra jet-Z™ CQB and CQBS suppressors are lightweight,ultra-compact rifle suppressors.

Manufactured in Finland by Ase Utra OY, the jet-Z™CQB and CQBS suppressors incorporates Ase Utra's patented jet-Z™baffle system.

The jet-Z™ CQB and CQBS are all-steel, all-welded units.

The jet-Z™ CQB adds only 484 to 505 grams net weight and 125 mm added length to a typical rifle and the CQBS is even smaller and lighter at 411-432grams and an added length of 96 mm.

With a diameter of just 40 mm, the suppressors are slim enough to be used with low-mounted telescopic or iron sights.

The jet-Z™ CQB and CQBS are available with a variety of internal threads to fit directly onto the rifle barrel.

Standard threads include for example; M14x1, M17x1, M18x1 ½"x20UNF, ½"x28 UNEF to fit most current centrefire rifles.

Other threads are also available.


The jet-Z™CQB and CQBS suppressor reduces sound pressure level by 28-32 dB (A) (depending on calibre 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.

Rifles tested with the jet-Z™ CQB and CQBS suppressor comply with the new personal noise exposure limit set by European Directive 2003/10/EC (140 Pa or137 dB(C)).

* 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.
