Brevis® II Ultra 5.56 Nato Rifle Suppressor


This suppressor is likely the lightest 5.56 NATO suppressor available. The Brevis II 5.56 grew from the concept of offering a fully functional sound and flash suppressor within 2X of the length and weight envelope of a traditional 5.56 flash hider. Despite its short length, this suppressor supplies performance appropriate for full length suppressors. The suppressor offers extremely light weight while at the same time possessing excellent durability.

The Brevis II 5.56 Ultra is 7.5 oz. and 3.7 in overall length. It is constructed of one monolithic piece of high strength Titanium alloy with its blast surface reinforced with a proprietary high nickel superalloy. The Brevis II 5.56 Ultra is our shortest and lightest 5.56 Nato offering.

As with the other Brevis II suppressors, the suppressor may be installed as a replacement muzzle device to the rifle. It is possible to service the rifle barrel with the suppressor attached.

Brevis® II 5.56 Nato Rifle Suppressor


The Brevis II 5.56 grew from the concept of offering a fully functional sound and flash suppressor within 2X of the length envelope of a traditional 5.56 flash hider. In addition to this short length, this suppressor supplies performance appropriate for full length suppressors. The suppressor offers very light weight while at the same time possessing unrivaled durability.

The BREVIS II 5.56 excels at weight, sound and visual signature reduction. The short overall length of 3.7 in. allows the Brevis II 5.56 to be employed in close quarters without a handling penalty. The overall length of the Brevis II 5.56 is close to that of two M16-A2 flash hiders. The BREVIS II is a true flash hider replacement that performs as part of the host system. With a lifespan similar to that of the barrel, this suppressor is rated for select fire use and performs well with 5.56 NATO barrels as short as 7.5 in.

The suppressor is constructed in its entirety of a single piece of proprietary hardened Inconel alloy vs. a collection of individual parts. This suppressor possesses a weight (11.5 oz.) only previously seen with titanium suppressors. This construction allows the Brevis II 5.56 to be manufactured without welds, threaded connections, press fittings or other traditional points of failure previously seen with suppressors.

The Brevis II 5.56 is designed to be able to be fielded as an armorer level installation that may be left on the host barrel. The host barrel may be serviced with the suppressor attached. The standard NATO 19mm wrench flats allow for a consistent torque during installation.

As with all Brevis II suppressors, the materials are extremely corrosion resistant and come standard with a high temp infrared absorptive ceramic coating.

Brevis® II Ultra 6.5MM Rifle Suppressor


It is said that competition improves the breed. The Brevis II 6.5 Ultra is a direct result of refinement derived from applied knowledge gained in competition. The short overall length and small diameter is reminiscent of a .22 rimfire suppressor. The concept of this suppressor is to produce a product that provides an edge to the competitor vs. a compromise.

In developing this suppressor, we relied on the input of competitors and their needs for a muzzle device. This suppressor provides excellent sound suppression with a length of 5.5” (4.9” added to barrel length). The suppressor is rated for 6.5mm rifle rounds including 6.5 Lapua, 6.5 x 47, .260 and similar rounds. The Brevis II 6.5 Ultra is designed to function as an effective muzzle brake consistent with competitor needs/expectations. In addition, accuracy was a primary consideration, propulsion gas management relative to projectile location was a major concern.

As with the other suppressors in the Brevis II line, the light weight (sub 7.5 oz) and compact size make the suppressor a replacement muzzle device that can be installed and left on. The barrel may be maintained with the suppressor installed.

The Brevis II 6.5mm Ultra is made of one homogeneous piece of high strength titanium alloy coupled with an integrated erosion resistant blast surface of hardened high nickel super alloy. As with most systems, removing complexity speaks directly to reliability and consistency.

Brevis® II 7.62 NATO Rifle Suppressor


The Brevis II 7.62 is a pinnacle in the refinement of the 7.62 muzzle mount suppressor. The 7.62 Brevis II introduces a fully hardened Inconel suppressor with a weight (16 oz.) similar to the expected weight of a 7.62 titanium suppressor. Even with the light weight and short overall length of 5.5” (4.9” added to barrel length) the Brevis II 7.62 displays outstanding performance. This suppressor provides flash reduction similar to if not exceeding most dedicated OEM flash hiders. In addition, sound reduction is superb, with a unique soft, deep tone.

The lifespan of this suppressor is similar to barrel life of the host weapon. The entire suppressor is constructed as a single homogeneous part without welds, threaded connections, seams or other traditional failure points.

As a precision rifle suppressor, this suppressor is consistent, accurate, and may be permanently installed on the host platform. The barrel may be maintained with the suppressor installed allowing the suppressor to function as a replacement muzzle device. Internal geometry is specifically designed to enhance accuracy while minimizing weapon signature through unique internal geometry and patented distribution of available internal volume.

Consistent, durable, lightweight, and compact: the Brevis 7.62 enhances the 7.62 platform as nothing before.

Brevis® II Ultra 7.62 NATO Rifle Suppressor


The Brevis II 7.62 Ultra brings a sub 10 oz. weight to a full function 7.62 x 51 suppressor. This suppressor is entirely a single piece of high strength heat treated titanium alloy coupled with a superalloy high nickel blast area. There are no welds, threaded connections, press fitments or other traditional modes of failure associated with suppressor construction.

As a muzzle mount suppressor, the ergonomic of the Brevis II 7.62 Ultra are without peer. An added length to the barrel of 4.9 in. and a dramatic reduction in cantilevered weight mean this suppressor may be installed and forgotten.

Recoil, flash, and sound reduction are excellent, with a unique deep, smooth tone to the report. As with all Brevis II suppressors, the application of symmetric internal geometry and discrete management of available volume minimize propellant turbulence upon the projectile.

The barrel may be maintained with the suppressor and most rifles will fit in the case with this short suppressor installed.

Consistency, extreme durability, compact envelope, outstanding performance, weight reduction have been combined in the Brevis II 7.62 Ultra. Let it readjust your perception of a 7.62 rifle suppressor.

Brevis® II Ultra 8.6mm Rifle Suppressor


The Brevis II Ultra 8.6mm is a new take on the big bore rifle suppressor. This suppressor transforms the typical perception of a suppressor for the .338 Lapua and similar rifles into something that may be considered a part of the rifle system. The 5.5” overall length (4.9” added to the length of the barrel) makes this a replacement muzzle device vs. an afterthought. The sub 10oz. weight means that carry and cantilevered weight are minimized to single multiples of most existing muzzle brakes and flash hiders. This suppressor offers durability similar to barrel lifespan. Barrel maintenance may be performed with the suppressor attached.

These attributes allow the Brevis II Ultra 8.6mm suppressor to be an armorer installed compliment to the rifle. Gone are the heavy and complex brakes and quick attach devices. This allows the rifle operator to have confidence in the accurate performance of their platform.

The Brevis II Ultra 8.6 is rugged and durable. This highly effective suppressor completely removes multiple part assembles and replaces them with a suppressor consisting of a single part: without welds, threaded attachments or other traditional failure points.

For those looking to couple brutal ruggedness with light weight and exceptional performance, the Brevis II 8.6mm delivers.
