Micro Streamer

For customers who want to have a rifle that is as short and light as possible we developed our Micro Streamer, which almost delivers the feel of a muzzle brake, but still reduces the signature significantly and makes short rifles safe to shoot without double hearing protection indoors. Streamer Micro is considerd more like a blast shield but it also suppress sound very effectively. It will deflect the sound forward instead of to the sides like muzzle brake. This will also be more pleasant to your colleagues when shooting side by side.

Measured sound pressure** (LCPeak) next to shooter’s right ear:

AR15, 223 Rem, 16″ barrel, 141,2 dB
CZ Scorpion Evo, 9mm, subsonic 132 dB
Remington 700, 308 Win, 24” barrel, 138 dB
Heckler & Koch MR308, 16” barrel, 143 dB


Sound suppression 10-15 dB
Modular and multicaliber construction
Flow through design – No need for adjustable gas blocks or other modifications to the rifle
No harmful toxic gases to shooters face and lungs
No increased weapon fouling
Full-auto rated with stainless steel body – Simple structure with advanced heat management.
Passes the SOCOM stress test cycles
Recoil management – No significant increase in bolt velocity
Serviceable – can be easily disassembled for cleaning and all parts can be changed
Caliber can changed by changing the suppression unit
No minimum barrel length restrictions
Flash suppression – Controlled gas flow technology and rapid gas flow cooling eliminates virtually all flash. For SBR rifles less than 16″ barrels we recommend compact Streamer or Streamer. Streamer suppressors are ideal when using night vision since they prevent night vision blooming with each pull of the trigger
Simulation unit available (for FX Simunition and Ultimate Training Munition UTM)


Gasflow/taperlock. Suppressor thread tightens automatically when shooting. Fast revolving gases inside the suppressors creates rotational force keeping the suppressor firmly seated. Taper mount at the front of the muzzle device locks and effectively seals the suppressor keeping the mounting surfaces and thread clean from carbon buildup.

Minimal and repeatable point of impact change. Streamers use direct thread mount with taper lock.

This design is least affected with POI shift because the suppressor indexes at the same point when mounted and remounted every time. Streamers baffleless design inside the suppressor is symmetrical. The bullet flying inside the suppressor is affected by gas pressure symmetrically from all directions which keeps the bullet trajectory always the same. In most cases point of impact shift is 1-4 cm and straight down (100m).

* Caliber and barrel lenght affects the result. See the measured results.
** Measured with Norsonic 131 Class 1 (precision) sound level meter and Gras 1/4″ microphone.
