Ase Utra Jet Z CQB BoreLock

The Ase Utra jet-Z CQB-BL suppressor is a robust, compact suppressor designed for professional use on .223 Rem / 5.56 mm NATO calibre rifles.

£540.00 Inc. VAT

We like this suppressor for its size (bigger brother to the CQBS-BL), solid build and performance on the AR 15 rifles. In addition, various BoreLock mounts are available allowing you to adapt the suppressor to several rifles. This keeps your costs down as you can have one suppressor which will fit on your rifles of .223 Rem calibre and under.

BoreLock mounts can be found on the web shop.

Whilst not quite as efficient as its bigger brother, it comes in at around 85 grams lighter and 30mm shorter which gives it the advantage in handling.

Manufactured in Finland by Ase Utra OY, the CQB-BL is an all-steel, all-welded unit incorporate Ase Utra's patented jet-Z baffle system and is rated for professional use on semiautomatic and select fire weapons.

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

In addition to the reduction in sound signature, the suppressor also reduces recoil and eliminates muzzle flash, so minimises disturbance particularly useful when hunting.

Recommended accessory for the suppressor is the Ase Utra cover made from Nomex and Cordura.
