A special suppressor for profes­sional users.

High-perfor­mance suppressor for firearms in .223 / cal. 5.56 mm 

The STAC1 is made of a heat-resis­tant Inconel alloy, manu­fac­tured using a 3D printing process, and offers maximum corro­sion resistance.

The “Flow Through” flow design ensures near-complete elim­i­na­tion of the muzzle signature.

The bolt carrier’s cyclic rate is barely increased, which is why the suppressor is also suit­able for (semi-)automatic firearms without adjustable
gas regu­la­tion.

“Blow­back” is also signif­i­cantly reduced, resulting in less expo­sure for the shooter to irri­tating and toxic emissions.

Tech­nical data: length 163 mm, diam­eter Ø 44 mm, weight 480 g, sound reduc­tion: 22.2 dB

The suppressor features a completely newly devel­oped ERATAC® LOC safety lock with auto­matic locking.

The sepa­rately avail­able barrel adapter features an inte­grated flash hider.

A high-perfor­mance coating minimises the adhe­sion of powder residue, and the dreaded “carbon lock” is reli­ably prevented. In addi­tion, a new muzzle brake will also be available.

To protect the ERATAC® LOC thread when the suppressor is removed.

Load capacity was tested to USSOCOM (United States Special Oper­a­tions Command) stan­dards. A total of 1,440 rounds are fired in rapid sequences up to sustained auto­matic fire. 

Func­tional perfor­mance and sound reduc­tion were confirmed by DEVA.

The balls ensure absolutely recoil-proof, play-free posi­tioning on the ERATAC® rails.

Using a side-oper­ated slider, the slider can be conve­niently unlocked while in position.
